Polymorphism of 2,5-[(di­phenyl­phosphan­yl)meth­yl]-1,1,2,4,4,5-hexa­phenyl-1,4-diphospha-2,5-dibora­cyclo­hexa­ne

2,5-[(Di­phenyl­phosphan­yl)meth­yl]-1,1,2,4,4,5-hexa­phenyl-1,4-diphospha-2,5-dibora­cyclo­hexane shows polymorphism as two tetra­hydro­furan (THF) disolvates [C₆₄H₅₈B₂P₄·2C₄H₈O, (Ia) and (Ib)] and pseudo-polymorphism as its toluene mono­solvate [C₆₄H₅₈B₂P₄·C₇H₈, (Ic)]. In each of polymorphs (Ia) and (Ib), the diphosphadibora­cyclo­hexane mol­ecule is located on a centre of inversion. The THF mol­ecule of (Ib) is disordered over two sites, with a site-occupation factor of 0.612 (8) for the major-occupied site. Both structures crystallize in the same space group (P2₁/n), but they display a different crystal packing. For pseudo-polymorph (Ic), although the space group is P2₁/c, which is just a different setting of the P2₁/n space group of (Ia) and (Ib), the crystal packing is completely different. Although the crystal packing in these three structures is significantly different, their mol­ecular conformations are surprisingly the same.

S1. Introduction

Multidentate ligand systems have attracted considerable inter­est in recent decades. Prominent examples of this class of ligands are the (pyrazol-1-yl)borates (scorpionates) [R_nBpz_4-n]^- (R = H, alkyl, aryl; n = 2, 1, 0; pz = pyrazol-1-yl) (Trofimenko, 1993, 1999; Bieller et al., 2004, 2005, 2006; Zhang et al., 2004, 2007; Morawitz et al., 2008a,b). Scorpionates have found a wide range of chemical applications, from modelling the active site of metalloenzymes, through analytical chemistry and organic synthesis to catalysis and materials science (Adams & Cotton, 1988). One way to alter the donor/acceptor properties of scorpionate ligands over a wider range is to replace the pyrazolyl rings by phospho­rus-containing groups. Similar to parent scorpionates, these ligands provide a monoanionic tridentate face-capping coordination mode, but they differ from parent scorpionates with regard to the softness of their donor sets. Recently, we have reported on the syntheses of the hybrid scorpionates [ArBpz_x(CH₂SMe)_3-x]^- (Ar = Ph, C₆H₄SiMe₃), which were achieved by transamination of [ArB(CH₂SMe)Br]₂ and [ArB(CH₂SMe)₂]₂, respectively, with a mixture of pyrazole and alkali metal pyrazolide (Ruth et al., 2008). The starting materials for this approach, the heterocycles [ArB(CH₂SMe)Br]₂ and [ArB(CH₂SMe)₂]₂ (Ar = Ph, C₆H₄SiMe₃), were prepared from ArBBr₂ and one or two equivalents of Li[CH₂SMe]. Therefore, we asked ourselves the question if it is possible to synthesize the related phosphanyl­methyl-substituted scorpionates [PhBpz_x(CH₂PPh₂)_3-x]^- via the corresponding heterocycles [PhB(CH₂PPh₂)Cl]₂ and [PhB(CH₂PPh₂)₂]₂, respectively, from PhBCl₂ and Li[CH₂PPh₂].

Unfortunately, the reaction of PhBCl₂ with unsupported and tmeda-supported (tmeda is tetra­methyl­ethylenedi­amine) Li[CH₂PPh₂] gave, in all cases, a mixture of [PhB(CH₂PPh₂)][PhBCl₂]₂, [PhB(CH₂PPh₂)₂]₂ and Li[PhB(CH₂PPh₂)₃].

The addition compound [PhB(CH₂PPh₂)₂][PhBCl₂]₂ (Müller et al., 2014a) could be isolated from the solution of a 1:1 reaction of PhBCl₂ with unsupported Li[CH₂PPh₂] (Fink et al., 2014; Ruth et al., 2007). The heterocycle [PhB(CH₂PPh₂)₂]₂, (I), was obtained from the reaction of PhBCl₂ with tmeda-supported Li[CH₂PPh₂]. X-ray quality crystals of (I) were grown from THF [polymorphs (Ia) and (Ib) were obtained from THF, the first at 238 K and the second at room temperature), as well as from toluene [pseudo-polymorph (Ic)]. Treatment of PhBCl₂ with three equivalents of tmeda-supported Li(tmeda)[CH₂PPh₂] led to the replacement of all Cl substituents by (di­phenyl­phosphanyl)methyl groups and consequently to the addition of the third one. In this context, it should be noted that the scorpionate Li(tmeda)₂[PhB(CH₂PPh₂)₃] (III) (Steinborn et al., 1998) can be transformed into the heteroscorpionate Li(tmeda)[PhBpz₂(CH₂PPh₂)] (Müller et al., 2014b) by the reaction of Li(tmeda)₂[PhB(CH₂PPh₂)₃] with two equivalents of pyrazole.

S2. Experimental

S2.1. Synthesis and crystallization

For the synthesis of [PhB(CH₂PPh₂)₂]₂, (I), a solution of PhBCl₂ (0.10 mmol, 116 mg) in toluene (3 ml) was added to a cooled (195 K) mixture of a tmeda-supported Li(tmeda)[CH₂PPh₂] (0.22 mmol, 203 mg) in Et₂O (25 ml). The mixture was stirred for 1 h at 195 K and then warmed to room temperature. After removal of all volatiles in vacuo from the filtered reaction solution, the residue was extracted into THF (5 ml). Single crystals of (I) with two additional molecules of THF [i.e. (Ib)] were grown from this THF solution at 238 K (yield 40%). Remark: single crystals of a polymorph [i.e. (Ia)] were grown from a THF solution at room temperature. X-ray quality crystals of the toluene solvate [i.e. (Ic)] were obtained from toluene at room temperature.

S2.2. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 1. H atoms were refined using a riding model, with aromatic C—H = 0.95 Å, methyl C—H = 0.98 Å or methyl­ene C—H = 0.99 Å and with U_iso(H) = 1.5U_eq(C) for methyl groups or 1.2U_eq(C) otherwise. The methyl group of the toluene molecule in (Ic) was allowed to rotate but not to tip.

The THF solvent molecule in (Ib) is disordered over two sites, with a site-occupation factor of 0.612 (8) for the major occupied site. The displacement ellipsoids of the disordered atoms were restrained to an isotropic behaviour. The C—C and C—O distances, respectively, involving the disordered atoms were restrained to be equal.

The structure of (Ic) shows pseudosymmetry. PLATON (Spek, 2009) detects a pseudo-translation operation, i.e. a pseudo-I-centring. However, only 83% of the atoms comply with this pseudosymmetry element.

S3. Results and discussion

The asymmetric unit of polymorph (Ia) (Fig. 1) contains half a molecule of the title compound and one molecule of THF. The molecule is located on a centre of inversion (Fig. 1). The B atoms are almost ideally tetra­hedrally coordinated [103.74 (14)–114.13 (17)°]. For the P atoms, some minor distortion can be observed, especially for atom P2, where the lone pair significantly reduces the C—P—C angles [C21—P2—C31 = 99.30 (10)°, C21—P2—C2 = 102.60 (10)° and C31—P2—C2 = 102.14 (10)°]. The central six-membered B₂P₂C₂ ring adopts a chair conformation. The phenyl rings at the B atoms are in axial positions. The ring P atom, on the other hand, has one phenyl substituent in an axial the other in an equatorial position. The acyclic CH₂—P bonds are trans to the B—P bonds in the ring [P1—B1—C2—P2 = 176.41 (10)°].

In polymorph (Ib), the molecule (Fig. 2) is again located on a centre of inversion and there is one molecule of THF in the asymmetric unit. The B atoms are almost ideally tetra­hedrally coordinated [105.58 (13)–113.70 (16)°]. For the P atoms, some minor distortion can be observed, especially for atom P2, where the lone pair significantly reduces the C—P—C angles [C21—P2—C31 = 100.11 (9)°, C21—P2—C2 = 102.92 (9)° and C31—P2—C2 = 103.21 (9)°]. The central six-membered B₂P₂C₂ ring adopts a chair conformation. The phenyl rings at the B atoms are in axial positions. The acyclic CH₂—P bonds are trans to the B—P bonds in the ring [P1—B1—C2—P2 = 179.53 (9)°].

(Ib) is a polymorph of (Ia). Both structures crystallalize in the monoclinic crystal system with the same space group, i.e. P2₁/c. However, the cell parameters are rather different. Although, the a axis [12.5508 (6) Å for (Ia) and 12.3097 (6) Å for (Ib)] and the monoclinic angle [93.962 (4)° for (Ia) and 93.720 (4)° for (Ib)] are quite similar, the b [10.1916 (5) Å for (Ia) and 13.3629 (4) Å for (Ib)] and c [24.7009 (10) Å for (Ia) and 18.4243 (9) Å for (Ib)] axes differ significantly.

Furthermore, both polymorphs display a different crystal packing (Figs. 3 and 4). The central molecule in both packing diagrams is drawn in essentially the same orientation. The significant difference between the packing patterns of the two structures can be expressed by the dihedral angle between the planes of the two symmetry-equivalent B₂P₂C₂ heterocycles. Whereas the heterocycles are almost coplanar in (Ia) [18.78 (11)°], they are almost perpendicular in (Ib) [77.03 (4)°].

(Ic) (Fig. 5) is a pseudo-polymorph of (Ia) and (Ib). In the present case, there is one diphosphadibora­cyclo­hexane molecule together with one molecule of toluene in the asymmetric unit, both of which do not show any crystallographic symmetry. The B atoms are almost ideally tetra­hedrally coordinated [101.7 (2)–114.2 (3)° for B1 and 103.4 (3)–113.2 (3)° for B2]. For the P atoms, some minor distortion can be observed, especially for atoms P3 and P4, where the lone pair significantly reduces the C—P—C angles [C81—P3—C71 = 99.50 (17)°, C81—P3—C3 = 102.97 (17)° and C71—P3—C3 = 102.16 (17)°; C4—P4—C101 = 103.52 (17)°, C4—P4—C91 = 103.72 (17)° and C101—P4—C91 96.75 (16)°]. The central six-membered B₂P₂C₂ ring adopts a chair conformation. The phenyl rings at the B atoms are in an axial position of ring. The acyclic CH₂—P bonds are trans to the B—P bonds in the ring [P1—B1—C3—P3 = -176.54 (19)° and P2—B2—C4—P4 = 178.66 (18)°]. The space group of (Ic) is P2₁/c, which is just a different setting of the P2₁/n space group of (Ia) and (Ib). Nevertheless, apart from similar values for the b axis of (Ib) and (Ic) [13.3629 (4) and 13.4283 (6) Å, respectively], the cell parameters differ completely from those of (Ia) and (Ib).

In addition, the crystal packing (Fig. 6) is once again completely different, as in the previous two structures. The molecules inside of unit cell are in essentially the same orientation as in Figs. 3 and 5. The significant difference between the packing pattern between the two structures can again be expressed by the dihedral angle between the planes of the two symmetry-equivalent B₂P₂C₂ heterocycles, which is either 0° for inversion-related molecules or 37.39 (5)° for glide-plane- or screw-axis-related molecules.

In contrast to the different packing patterns in the three described structures, the molecular conformation of the molecule is essentially the same in all three structures. A least-squares fit (superimposing the central six-membered rings) of the three structures (Fig. 7) shows the striking similarities between the molecular conformations, which are essentially the same in all three cases.

Concluding, it can be said, that the title compound tends to form polymorphic crystal structures and it can be assumed that other (pseudo-)polymorphs might be found.

Special details

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

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.

Special details

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

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.

Special details

Experimental. ;

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

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
