Crystal structures of ten phosphane chalcogenide complexes of gold(III) chloride and bromide

Phosphane chalcogenides and their metal complexes, Part 7. Part 6: Upmann et al. (2024).

The structures of ten phosphane chalcogenide complexes of gold(III) halides, with general formula R¹_3–nR²_nPEAuX₃ (R¹ = t-butyl; R² = i-propyl; n = 0 to 3; E = S or Se; X = Cl or Br) are presented. The eight possible chlorido derivatives are: 9a, n = 3, E = S; 10a, n = 2, E = S; 11a, n = 1, E = S; 12a, n = 0, E = S; 13a, n = 3, E = Se; 14a, n = 2, E = Se; 15a, n = 1, E = Se; and 16a, n = 0, E = Se, and the corresponding bromido derivatives are 9b–16b in the same order. Structures were obtained for 9a, 10a (and a second polymorph 10aa), 11a (and its deutero­chloro­form monosolvate 11aa), 12a (as its di­chloro­methane monosolvate), 14a, 15a (as its deutero­chloro­form monosolvate 15aa, in which the solvent mol­ecule is disordered over two positions), 9b, 11b, 13b and 15b. The structures of 11a, 15a, 11b and 15b form an isotypic set, and those of compounds 10aa and 14a form an isotypic pair. All structures have Z′ = 1. The gold(III) centres show square-planar coordination geometry and the chalcogenide atoms show approximately tetra­hedral angles (except for the very wide angle in 12a, probably associated with the bulky t-butyl groups). The bond lengths at the gold atoms are lengthened with respect to the known gold(I) derivatives, and demonstrate a considerable trans influence of S and Se donor atoms on a trans Au—Cl bond. Each compound with an isopropyl group shows a short intra­molecular contact of the type C—H_methine⋯X_cis; these may be regarded as intra­molecular ‘weak’ hydrogen bonds, and they determine the orientation of the AuX₃ groups. The mol­ecular packing is analysed in terms of various short contacts such as weak hydrogen bonds C—H⋯X and contacts between the heavier atoms, such as X⋯X (9a, 10aa, 11aa, 15aa and 9b), S⋯S (10aa, 11a and 12a) and S⋯Cl (10a). The packing of the polymorphs 10a and 10aa is thus quite different. The solvent mol­ecules take part in C—H⋯Cl hydrogen bonds; for 15aa, a disordered solvent region at z ≃ 0 is observed. Structure 13b involves unusual inversion-symmetric dimers with Se⋯Au and Se⋯Br contacts, further connected by Br⋯Br contacts.

1. Chemical context

In Part 6 of this series (Upmann et al., 2024), we presented the structures of sixteen halogenido-gold(I) complexes of various tri­alkyl­phosphane chalcogenides. Appropriate background material, together with a summary of our previous results, can be found in that publication and is not repeated here.

In this paper, we report the structures of ten tri­alkyl­phosphane chalcogenide complexes of gold(III) trihalides, with general formula (^tBu_3–nⁱPr_nP=E)AuX₃, of which there are sixteen possible permutations of n, the chalcogenide E (restricted to S or Se) and X (for X = Cl or Br; tri­iodido complexes are generally not accessible). The eight theoretically obtainable tri­chlorido derivatives are: 9a, n = 3, E = S; 10a, n = 2, E = S; 11a, n = 1, E = S; 12a, n = 0, E = S; 13a, n = 3, E = Se; 14a, n = 2, E = Se; 15a, n = 1, E = Se; and 16a, n = 0, E = Se, and the corresponding tri­bromido derivatives are 9b–16b in the same order. These are generally obtained from the gold(I) precursors (numbered analogously as 1a–8a and 1b–8b in our previous publication; Upmann et al., 2024) using one mole equivalent of elemental bromine or PhICl₂ [commonly known as iodo­benzene dichloride; systematic name di­chloro­(phen­yl)-λ³-iodane] as oxidizing agents. However, ^tBu₃P = SeAuCl, 8a, was found to be unstable, thus ruling out the preparation of 16a; 13a also proved to be unstable; and the attempted syntheses of 10b, 12b, 14b and 16b led to different products, to be described in future publications. This left ten successfully synthesized compounds, leading to thirteen structures; 10a was obtained as two polymorphs (the second termed 10aa), whereas structures of 11a and 15a were determined both solvent-free and as the deutero­chloro­form monosolvates 11aa and 15aa. Compound 12a was obtained as a di­chloro­methane monosolvate. The structures of 10a, 11a, 14a and 15aa were briefly presented in a preliminary communication (Upmann & Jones, 2013), but have been re-refined using a much more recent version of SHELXL (2019 rather than 1997; Sheldrick, 2015) and are discussed in more detail here. Details of the composition of each compound studied are given in Table 1.

We had earlier synthesized all four permutations (E = S or Se, X = Cl or Br) of Ph₃PEAuX₃ (Taouss et al., 2015), but were unable to determine any of the structures because of extensive ‘streaking’ of the diffraction images.

2. Structural commentary

General comments: All compounds crystallize with one formula unit in the asymmetric unit. The mol­ecular structures are shown in Figs. 1–13; selected mol­ecular dimensions are given in Tables 2–14. The trans (to E) halogen atoms are numbered as X1 throughout. All comparisons to the analogous series of gold(I) compounds refer to our previous paper (Upmann et al., 2024). As expected, all compounds show square planar coordination geometry (angle ranges ca 87–95 and 172–179°) at the gold(III) centres; the largest mean deviation from the plane containing the gold atom and all donor atoms is 0.078 Å for 11b. The approximately tetra­hedral angles (except for 12a) at the chalcogenide atoms would also be expected (discussed below in more detail).

Isotypy: In an extensive series of closely analogous structures, several would be expected to be isotypic. Indeed, the four compounds 11a, 15a, 11b and 15b form an isotypic set, and compounds 10aa and 14a form an isotypic pair.

Bond lengths and angles (1). P—E—Au—X₃ groups: The P—S and P—Se bond lengths lie in the ranges 2.0523–2.0665 (av. 2.0602) and 2.2085–2.2247 (av. 2.2183) Å, respectively, significantly longer than in the gold(I) derivatives (av. 2.0368 and 2.1938 Å, respectively); this further lengthening with respect to the ‘standard’ bond lengths of ca 1.95 and 2.11 Å, respectively, in the free ligands implies a slightly higher contribution of the ‘resonance’ form with a P—E single bond to the overall bonding. The bond lengths at the gold atoms are in general considerably lengthened with respect to the gold(I) derivatives; the average bond lengths (Å), with the corres­ponding Au^I values in square brackets, are Au—S 2.3337 [2.2760], Au—Se 2.4494 [2.3845], Au—Cl trans to E 2.3107 [2.2840], cis to E 2.2855, Au—Br trans to E 2.4471 [2.3979], cis to E 2.4336.

The considerable trans influence of S and Se donor atoms on a trans Au—Cl bond is striking. Thus the six Au—Cl bonds trans to S have an average length of 2.3054 Å, with twelve shorter cis bond lengths, average 2.2857 Å; three Au—Cl bond lengths trans to Se have an average length of 2.3213 Å, with six shorter cis bond lengths, average 2.2851 Å. However, few other clear trends can be recognized; the Au—S and Au—Se bonds are slightly longer trans to Br (av. 2.3445 and 2.4571 Å) than trans to Cl (av. 2.3301 and 2.4443 Å), but the differences and the sample sizes are both small. This would be consistent with similar trans influences for S, Se and Br.

The angles P—S—Au lie in the range 106.70–111.96 (av. 110.29°), with P—Se—Au = 107.24–108.49 (av. 108.08°). The angles are appreciably wider than for the Au^I derivatives (av. 106.17 and 103.86°). Here we have, however, excluded the extreme outlier 12a, with a P—S—Au angle of 117.50 (3)°, which we tentatively attribute to steric effects; 12a is the only ^tBu₃P=E derivative reported in this paper (see also Section 4).

Bond lengths and angles (2). Phosphane chalcogenide ligands: For the Au^I derivatives involving both types of alkyl groups, the carbon atom anti­periplanar to Au across the Au—E—P—C sequence generally belongs to an i-propyl group (the exceptions are the ^tBu₂ⁱPrP=E derivatives 3a and 3b). For the Au^III derivatives, however, all six structures involving such ligands have an anti­periplanar t-butyl group. Because of the bulky alkyl substituents at phospho­rus, most C—P—C bond angles are greater than the ideal tetra­hedral value. As compensation for this, the E—P—C angles to the carbon atom anti­periplanar to E are narrower, with values in the range 99.3–102.7°. The steric crowding is also reflected in several short intra­molecular contacts involving the hydrogen atoms. These are listed for convenience in the tables of hydrogen bonds. In particular, contacts of the type C—H⋯X_cis, invariably involving a methine hydrogen (except for the ^tBu₃P=S derivative 12a, which has no methine hydrogens), are short enough to be regarded as intra­molecular ‘weak’ hydrogen bonds; we suggest that the formation of these hydrogen bonds overrides the tendency for the i-propyl group to adopt the anti­periplanar position. The halogen atoms are numbered such that X3 is the intra­molecular hydrogen-bond acceptor. This hydrogen bond is drawn explicitly only for compound 9a (Fig. 1), although the C—H group pointing towards X3 can easily be recognized for several other compounds. Another effect associated with these hydrogen bonds is the consistent positioning of the AuX₃ group, with X—Au—E—P torsion angles of ca 65° for the hydrogen-bonded X atom and ca 115° (with the opposite sign) for the other cis X; again, the ^tBu₃P=S derivative 12a behaves differently, with X—Au—E—P torsion angles of 82.19 (3) and −100.28 (3)°. The C—H⋯Au contacts (the latter with H⋯Au as short as 2.68 Å) all involve methyl groups and could be regarded as an inevitable consequence of the crowding effects rather than any significant inter­action. This applies a fortiori to the short C—H⋯E contacts, which have very narrow angles at the hydrogen atom.

For the compounds with two structure determinations, least-squares fits were performed (for non-hydrogen atoms) using the program XP (Bruker, 1998). The r.m.s. deviations were 0.20 Å for 10a/10aa (0.10 Å if methyl carbon atoms were omitted; Fig. 14), 0.13 Å for 11a/11aa and 0.05 Å for 15a/15aa (the latter were fitted with one structure inverted).

Figure 14 A least-squares fit of structures 10a/10aa (the latter with dashed bonds). The fitted atoms (which exclude the methyl carbons) are labelled. The r.m.s. deviation is 0.10 Å for all fitted atoms (max. 0.23 Å for Cl3).

Mol­ecular volumes: For the gold(I) species, the change in mol­ecular volume (cell volume/Z) on changing the elements E or X (for the same phosphine) was calculated for six pairs S/Se and for six pairs Cl/Br. The values thus obtained were generally consistent with the atomic volumes calculated by Hofmann (2002), namely S 25.5, Se 30.3, Cl 25.8 and Br 32.7 ų. For the gold(III) series, fewer pairs are available, but the results are less convincing. The two polymorphs 10a/10aa already differ by 4.4 ų, which is comparable to the difference in volume between S and Se according to the density rule postulated by Kitaigorodskii (1961). More ‘rational’ (denser) crystal packing should correspond to a more stable polymorph, so that 10aa (D_x = 2.073 Mg m⁻³) should be more stable than 10a (D_x = 2.051 Mg m⁻³). For three pairs Cl/Br, the volume increases range from 13 to 20 ų, but for four pairs S/Se, the differences range from 1.5 to 7 ų and for the pair 9b/13b the difference has the wrong sign (the sulfur-containing 9b has a slightly larger volume, by 1 ų). Clearly such a simple additive model for the mol­ecular volumes does not apply well here.

3. Supra­molecular features

For general aspects of packing and types of secondary inter­action, as applied to these compounds, a series of general articles are quoted in our previous paper (Upmann et al., 2024). Hydrogen bonds are given in Tables 15–27; these include intra­molecular contacts (see above) and several borderline cases. The corresponding symmetry operators, not given explicitly in the following discussion, may also be found in those Tables. In all packing diagrams presented here, hydrogen atoms not involved in hydrogen bonding are omitted for clarity, and the atom labels indicate the asymmetric unit. It is worth repeating the caveat that X-ray methods reveal short inter­molecular contacts, but not the corresponding energies, so that descriptions of mol­ecular packing in terms of particular secondary contacts must to some extent be subjective. Similarly, there is no clear objective judgement, on the basis of contact lengths and angles, as to which contacts should be regarded as more important or less important for the packing. Finally, the exposed nature of the one-coordinate halogen atoms, combined with the large number of hydrogen atoms, means that some short H⋯X contacts are inevitable. Nevertheless, it is possible to obtain informative packing diagrams.

For compound 9a, five H⋯Cl contacts (from H1, H2, H3, H22A and H11C) combine to form a layer structure parallel to (011) (Fig. 15). A short Cl3⋯Cl3 contact of 3.625 (1) Å, operator 1 − x, −y, 1 − z, is also observed. We have previously noted the tendency of tetra­halogenidoaurate(III) anions to display short X⋯X contacts (Döring & Jones, 2016), and these are also observed in some neutral trihalogenidogold(III) complexes such as tri­bromido­(piperidine)­gold(III) (Döring & Jones, 2023).

Figure 15 Packing diagram of 9a, showing the formation of a layer structure parallel to (011) in the region y ≃ 0.25, z ≃ 0.25. Dashed lines indicate H⋯Cl contacts (thin) or Cl⋯Cl contacts (thick).

Compound 10a also forms a layer structure, parallel to the ac plane, involving three H⋯Cl contacts (from H13B, H13C and H32A) and one S⋯Cl contact [S1⋯Cl3(1 − x, 1 − y, 1 − z) = 3.6746 (9) Å] (Fig. 16). The second polymorph 10aa has a completely different packing; there are no H⋯Cl contacts < 2.94 Å, but instead the mol­ecules associate to form dimers (Fig. 17) with a short S1⋯S1 contact of 3.622 (2) Å (operator 1 − x, −y, 1 − z). The corresponding S1⋯Au1 distance is 4.0282 (8) Å, and there is a borderline H22C⋯Au1 contact of 3.18 Å. Dimers are linked to form a chain parallel to the a axis by the contact Cl2⋯Cl3 3.5885 (11) Å (operator −1 + x, y, z; Fig. 18). The packing of 11a is similar to that of 10a, again involving inversion-symmetric dimers [S1⋯S1 = 3.4257 (9), S1⋯Au1 = 4.0467 (5), H21C⋯Au1 = 3.03 Å, operator 1 − x, 1 − y, −z], but with these being linked by the contact H13⋯Cl2 to form chains parallel to the c axis (Fig. 19). Compound 14a (isotypic to 10aa) has contact distances Se1⋯Se1′ = 3.615 (2) and Cl2⋯Cl3′ = 3.511 (3) Å. Compounds 11b, 15a and 15b (isotypic to 11a) have distances Se1⋯Se1′ = 3.3447 (4), S1⋯S1′ = 3.4513 (11) and Se1⋯Se1′ = 3.3734 (5) Å, respectively. The primes indicate the operators given above for the parent structures.

Figure 18 Structure 10aa: Association of dimers to form chains parallel to the a axis. The two chains lie in the regions y ≃ 0.5, z ≃ 0 and y ≃ 0, z ≃ 0.5. Thick dashed lines indicate Cl⋯Cl and S⋯S contacts; the latter are viewed almost end-on. Hydrogen atoms are omitted.

For compound 11aa, which is the deutero­chloro­form solvate of 11a, the solvent mol­ecule is well-ordered, and its deuterium atom is involved in a three-centre hydrogen bond to Cl1 and Cl2. The residues are further linked by the short contact Cl3⋯Cl6 = 3.6706 (7) Å (operator x, −1 + y, z), forming chains parallel to the b axis (Fig. 20). There are no H⋯Cl contacts < 2.91 Å.

Compound 12a, which is a di­chloro­methane solvate, has a three-dimensional packing in which the most striking feature is the formation of dimers via the contact S1⋯S1(1 − x, 1 − y, 1 − z) = 3.4357 (10) Å. The packing involves layers parallel to (011); these include the solvent contacts H99A⋯Cl2 (also shown in Fig. 6) = 2.84, H99B⋯Cl3 = 2.96 and Cl5⋯Cl5(2 − x, 2 − y, −z) = 3.3990 (14) Å (Fig. 21). The alkyl groups of one layer project into the gaps of neighbouring layers. The contacts H22A⋯Cl3 are not shown in Fig. 21.

Compound 15aa, the deutero­chloro­form solvate of 15a, has few short contacts between the mol­ecules of the gold complex itself; the contact Cl1⋯Cl1(−x, 2 − y, 1 − z) = 3.5208 (13) Å links the mol­ecules into simple dimers. Instead it is the disordered solvent, occupying the region at z ≃ 0, that lies between and thus connects the mol­ecules of the gold complex. Fig. 22 shows this pattern for the major disorder component, with D99⋯Cl2 = 2.76, Au1⋯Cl5 = 3.547 (2) and Cl2⋯Cl5 = 3.603 (2) Å (both −x, 2 − y, −z) and Cl6⋯Cl6 = 3.546 (6) Å (−x, 1 − y, −z). The minor component, somewhat displaced from its major counterpart [C99⋯C99′ = 0.59 (1) Å, angle between C—D vectors = 9°], makes a similar series of contacts, which we do not discuss explicitly.

Figure 22 Compound 15aa: The disordered solvent, only the major component of which is shown here, lies between the mol­ecules of the gold complex, forming a variety of short contacts Au⋯Cl, H⋯Cl and Cl⋯Cl (dashed lines). The view direction is perpendicular to the ab plane in the region x ≃ 0.

Compound 9b has a short Br1⋯Br3(−x,  + y,  − z) contact of 3.7110 (4) Å. This combines with four H⋯Br contacts and one H⋯Au contact to form a layer structure parallel to (10) (Fig. 23).

Figure 23 Compound 9b: The layer structure parallel to (10), formed by Br⋯Br contacts (thick dashed lines) and five weak hydrogen bonds (thin dashed lines).

The packing of compound 13b involves the formation of striking inversion-symmetric dimers, with short contacts Au1⋯Se1′ = 3.7472 (5) and Se1⋯Br3′ = 3.4874 (6) Å, via the operator 1 − x, 1 − y, −z (Fig. 24). The corresponding Au1⋯Au1′ and Au1⋯Br2′ distances of 4.1897 (3) and 4.0038 (5) Å are probably too long to represent any significant inter­action. The dimer formation is reminiscent of the stacking of AuX₃ moieties, as observed for example for the infinite stacks in four polymorphs of tri­chlorido­(tetra­hydro­thio­phene)­gold(III) (Upmann & Jones, 2017), but with the important difference that the Se atom of 13b is also involved. The dimers are linked by a short Br2⋯Br3 contact of 3.5478 Å (operator 1 + x, y, z), forming a chain parallel to the a axis (Fig. 25).

4. Database survey

The searches employed the routine ConQuest (Bruno et al., 2002), part of Version 2022.3.0 of the Cambridge Structural Database (Groom et al., 2016).

A search for all structures containing the moiety R₃P=S—TM (coordination numbers of 4 for P and 2 for S, bond orders unspecified, TM = any transition metal), excluding any structure in which the P=S or S—TM bonds were involved in rings, gave 83 hits. The 108 bond angles at sulfur ranged from 95.6–127.9°, so that this angle is clearly highly variable. The largest value of 127.88 (2)° was observed for the only structure involving ^tBu₃P=S, namely [(^tBu₃PS)Fe(CO)₂Cp][PF₆] (RIDJUK; Kuckmann et al., 2007), cf. structure 12a above. Similarly, 39 hits for R₃P=Se—TM were registered, with 58 angles at selenium in the range 92.1–113.3°. One of the smallest angles, 92.91 (12)°, was observed for (9-phenanthr­yl)Ph₂PSeAuCl (as its benzene solvate); the analogous sulfur derivative (solvent-free) had a P—S—Au angle of 100.85 (6)° (DUGSAB & DUGFOC; Breshears et al., 2015).

Searches for other compounds of the type (R₃P=E)AuX₃ gave only our own structures, i.e. all four permutations (E = S or Se, X = Cl or Br) of (PCP)ⁱPr₂EAuX₃ (PCP = [2.2]para­cyclo­phanyl; Upmann et al., 2019).

5. Synthesis and crystallization

For several of the compounds, the syntheses can be found in the PhD thesis of D. Upmann (Upmann, 2015). The following do not appear there:

Compound 9a. 125 mg (0.3 mmol) of ⁱPr₃PSAuCl were dissolved in 5 mL of di­chloro­methane, and a solution of iodo­benzene dichloride (82 mg, 0.3 mmol) in 5 mL of di­chloro­methane was added. The red solution was stirred for 30 min. The solvent was removed under vacuum. The product, a red solid, was precipitated with n-pentane and dried under vacuum. The yield was not recorded. ³¹P-NMR (200 MHz, CDCl₃, 300 K): δ (ppm) 78.64 (s). Elemental analysis (%): calculated: C 21.81, H 4.27, S 6.47; found: C 22.06, H 4.07, S 6.26. Single crystals were obtained by liquid diffusion of n-pentane into a solution of 9a in di­chloro­methane. Similar attempts to synthesize the selenium analogue (which would have been compound 13a) were unsuccessful; the product was always an intra­ctable gum that decomposed.

Compound 9b. 187.4 mg (0.399 mmol) of ⁱPr₃PSAuBr were dissolved in 3 mL of di­chloro­methane, and 4.16 mL of a 0.096 M solution of bromine in di­chloro­methane were added. The product, a red solid, was precipitated with n-pentane and dried under vacuum. Yield: 132.6 mg (0.211 mmol, 53%). ³¹P-NMR (81 MHz, CDCl₃, 300 K): δ (ppm) 77.17 (s). Elemental analysis (%): calculated: C 17.19, H 3.37, S 5.10; found: C 17.42, H 3.40, S 5.31. Single crystals were obtained by liquid diffusion of n-pentane into a solution of 9b in di­chloro­methane.

Compound 11b. 336 mg (0.675 mmol) of ⁱPr₂^tBuPSAuBr were dissolved in 3 mL of di­chloro­methane, and 6.7 mL of a 0.1 M solution of bromine in di­chloro­methane were added. The solution was overlayered with n-pentane and stored in a refrigerator (278 K) overnight. Crystals suitable for structure determination formed. After removal of the solvent under vacuum, the product was recrystallized from a mixture of di­chloro­methane and n-pentane as a dark-red solid. Yield: 341 mg (0.685 mmol, qu­anti­tative). ³¹P-NMR (81 MHz, CDCl₃, 300 K): δ (ppm) 85.18 (s). Elemental analysis (%): calculated: C 20.11, H 3.84, S 4.88; found: C 20.98, H 4.01, S 4.97.

Compound 12a was synthesized by the same general method as the other chloro derivatives (e.g. 9a, see above), but the details have unfortunately been lost.

Compound 13b. 194.7 mg (0.377 mmol) of ⁱPr₃PSeAuBr were dissolved in 3 mL of di­chloro­methane, and 3.93 mL of a 0.096 M solution of bromine in di­chloro­methane were added. The product, a red solid, was precipitated with n-pentane and dried under vacuum. Yield: 141.2 mg (0.209 mmol, 55%). ³¹P-NMR (81 MHz, CDCl₃, 300 K): δ (ppm) 74.46 (s, ¹J_P–Se = 520 Hz). Single crystals were obtained by liquid diffusion of n-pentane into a solution of 13b in di­chloro­methane. Elemental analysis (%): calculated: C 15.99, H 3.13; found: C 16.22, H 3.18.

Compound 15b. 303 mg (0.557 mmol) of ⁱPr^tBu₂PSeAuBr were dissolved in 3 mL of di­chloro­methane, and 5.6 mL of a 0.1 M solution of bromine in di­chloro­methane were added. The solution was overlayered with n-pentane and stored in a refrigerator (278 K) overnight. After removal of the solvent under vacuum, the product was recrystallized twice from a mixture of di­chloro­methane and n-pentane as a dark red solid, from which a crystal was selected for measurement. The yield was only ca 20%, and neither the elemental analyses nor the ³¹P-NMR results were satisfactory (despite the successful structure determination). We suspect partial decomposition of the product.

The conditions under which the polymorph 10aa arose were unfortunately not recorded. Crystals of the deutero­chloro­form solvates 11aa and 15aa were obtained fortuitously by evaporation from the corresponding NMR solutions.

6. Refinement

Details of the measurements and refinements are given in Table 28. Structures were refined anisotropically on F². Methine and methyl­ene hydrogens were included at calculated positions and refined using a riding model with C—H = 1.00 or 0.99 Å respectively and U_iso(H) = 1.2 × U_eq(C). Methyl groups were refined, using the command AFIX 137, as idealized rigid groups allowed to rotate but not tip, with C—H = 0.98 Å, H—C—H = 109.5° and U_iso(H) = 1.5 × U_eq(C). The use of this command determines the initial hydrogen positions (before refinement) by analysis of maxima in the residual electron density at suitable C—H distances, and these peaks may not be entirely reliable in the presence of a very heavy atom (although in general the refinement seemed to proceed satisfactorily), so that any postulated hydrogen bonds involving methyl hydrogen atoms should be inter­preted with caution.

Special features: The deutero­chloro­form mol­ecule of 15aa is disordered over two positions with occupation factors 0.525 (4) and 0.475 (4). Appropriate restraints were employed to improve refinement stability, but the dimensions of disordered groups should always be inter­preted with caution. The data for 14a were significantly affected by the presence of a small (and at first undetected) satellite crystal, rotated by ca 5° from the main crystal. Attempts to treat the structure using procedures developed for non-merohedral twins did not lead to any improvement, and no better crystals were found. The U values are significantly higher than for the other structures, and the ellipsoid plot (Fig. 7) is drawn at 30% rather than 50% levels.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
