Tetrameric triphenylsilanol, (Ph₃SiOH)₄, and the adduct (Ph₃SiOH)₂-di­methyl sulfoxide, both at 120 K, and the adduct (Ph₃SiOH)₄-1,4-dioxan at 150 K: interplay of O-H...O and C-H...[pi](arene) interactions

The structure of tetrameric tri­phenyl­silanol, C₁₈H₁₆OSi, (I), has been re-investigated at 120 (2) K. The hydroxyl H atoms were readily located and one of the arene rings is disordered over two closely positioned sets of sites. The mol­ecules are linked into cyclic tetramers, having approximate (S₄) symmetry, via O-H...O hydrogen bonds [H...O 1.81-1.85 Å, O...O 2.634 (3)-2.693 (3) Å and O-H...O 156-166°]. At ambient temperature, there are indications of multiple disorder of the phenyl-ring sites. In bis­(tri­phenyl­silanol) di­methyl sulfoxide solvate, 2C₁₈H₁₆OSi·C₂H₆OS, (II), the di­methyl sulfoxide component is disordered across a twofold rotation axis in C2/c, and the molecular components are linked by a single O-H...O hydrogen bond [H...O 1.85 Å, O...O 2.732 (2) Å and O-H...O 172°] into three-mol­ecule aggregates, which are themselves linked into a single three-dimensional framework by two C-H...[pi](arene) interactions. In tetrakis­(tri­phenyl­silanol) 1,4-dioxan solvate, 4C₁₈H₁₆OSi·C₄H₈O₂, (III), the 1,4-dioxan component lies across an inversion centre in space group P and centrosymmetric five-mol­ecule aggregates are linked by paired C-H...[pi](arene) interactions to form molecular ladders.

S1. Comment

We recently reported the structure analysis at 120 (2) K of catena-poly[[triphenyltin(IV)]-µ-hydroxo-κ²O:O], (Ph₃SnOH)_n; by use of a low-temperature dataset collected on a CCD diffractometer, the location of the hydroxyl H atom was readily achieved (Glidewell et al., 2002). By contrast, use of an ambient-temperature dataset collected using a four-circle diffractometer did not allow location of the hydroxyl H atom (Glidewell & Liles, 1978). We also noted (Glidewell et al., 2002) that the use of low-temperature CCD datasets should render possible the location of the hydroxyl H atoms in other Ph₃MOH compounds, in particular that in Ph₃SiOH, (I). This compound crystallizes in space group P1 with Z = 16, i.e. with Z' = 8 (Puff et al., 1991), and the molecules are arranged to form two independent cyclic tetramers, each having approximate 4 (S₄) symmetry. The short intermolecular O···O distances indicate the presence of O—H···O hydrogen bonds linking the molecules, but using data collected at 198 K on a four-circle diffractometer it did not prove possible to locate any of the eight hydroxyl H atoms (Puff et al., 1991). Furthermore, scrutiny of the original structure report reveals anomalously high U_eq values for several of the C atoms, two of which, moreover, were refined only isotropically. These facts, and the rather high residual densities, suggest some difficulties with the refinement model. This may, in turn, account for the rather high R value of 0.079 for only 12146 reflections, with 9079 labelled `observed' and used in the refinement, giving a reflections:parameters (n/p) ratio of only 6.35. The overall precision of the structure determination is thus rather modest [σ(Si—O) 0.005 Å, σ(Si—C) 0.007 Å, and σ(C—C) 0.007–0.026 Å, mean 0.015 Å]. \sch

We have therefore re-investigated (I), both at 120 (2) K and at ambient temperature. At both temperatures, the unit-cell dimensions, the space group and the atomic coordinates indicate the same phase as originally investigated by Puff et al. (1991). The same phase was obtained by crystallization from a wide range of solvents including toluene (as used in the original study); a crystal grown from chloroform solution gave marginally the best dataset, and it is the refinement based on these data that is reported here. Data collection at 120 (2) K resulted in a much larger dataset than previously employed, with an n/p ratio of 17.2. The hydroxyl H atoms were readily located from difference maps, but it was necessary to model one of the phenyl rings using two sets of sites, each with 50% occupancy. The overall supramolecular structure matches that reported earlier, based solely on O—H···O hydrogen bonds; there are neither C—H···π(arene) interactions nor aromatic π···π stacking interactions in the crystal structure of (I).

The principal structural features of (I) (Fig. 1), in which the C atoms are labelled as Cpqr, where the index p (= 1 to 8) defines the molecule, q (= 1 to 3) defines the ring within a specified molecule, and r (= 1 to 6) defines the atom within a specified ring, are identical with those reported earlier, but the key structural parameters (Table 1) are more precise [σ(Si—O) 0.002 Å, σ(Si—C) 0.003 Å and σ(C—C) 0.004–0.005 Å]. The hydrogen bonds (Table 2) in which all of the hydroxyl H are fully ordered at 120 (2) K are characterized by O···O distances which are short for simple neutral ROH species, and by O—H···O angles which are close to 160°. For comparison, the O···O distances in the tetrahedral tetramer (Ph₃COH)₄ are 2.859 (5) and 2.854 (5) Å at 113 K, and 2.905 (4) and 2.901 (4) Å at 293 K (Serrano-González et al., 1999). The hydroxyl H atoms in (Ph₃COH)₄ could not be located from ambient-temperature X-ray data (Ferguson et al., 1992); these H atoms are, in fact, mobile over a number of sites at ambient temperature (Aliev et al., 1998), and neutron diffraction at 100 K was required to locate these H sites unambiguously (Serrano-González et al., 1999).

Using data collected at 298 (2) from a crystal grown from toluene solution, so mimicking the original crystal preparation, we then investigated the ambient-temperature structure of (I). The overall tetrameric aggregation is unchanged and there were reasonably good indications, from difference maps, for at least some of the hydroxyl H atoms. However, not only was the diffraction intensity rather poor, with only 27.6% of the reflections labelled `observed' compared with over 60% at 120 (2) K, but there were indications of possible disorder in no fewer than eight of the 24 independent phenyl rings. Accordingly, refinement was not pursued. After completing this study, we learned of a recent unpublished determination at 123 K (Nieger, 2001), deposited in the Cambridge Structural Database (CSD; Allen & Kennard, 1993) as a private communication with CSD reference code JIPTIL01. The findings of this study appear to be identical with those reported here, although it is perhaps unfortunate that there are no anisotropic displacement parameters stored in the CSD files.

Crystallization of triphenylsilanol from dimethylsulfoxide (DMSO), on the other hand, leads to a 2:1 solvate, (Ph₃SiOH)₂·DMSO, (II) (Fig. 3). In (II), the silanol molecule lies in a general position in space group C2/c, and the DMSO molecule is disordered across a twofold rotation axis, such that it could be satisfactorily modelled using a single O site on the twofold axis, a single C site in a general position and two distinct S sites of 0.25 occupancy, corresponding to two confacial pyramidal orientations having common O and C sites on a shared face. Within the silanol molecule in (II), the Si—O distance (Table 3) is slightly shorter than those in (I), but the Si—C distances in (I) and (II) span comparable ranges with virtually identical mean values.

Whereas the intermolecular aggregation in (I) produces finite oligomers, compound (II) forms a continuous framework. The silanol atom O1 acts as a hydrogen-bond donor to the DMSO atom O2 (Table 4), so generating a three-molecule aggregate lying across a rotation axis (Fig. 4). There are four of these aggregates in each unit cell and they are linked into a single three-dimensional framework by means of two distinct C—H···π(arene) hydrogen bonds (Table 4). Atom C4 in the silanol molecule at (x, y, z) acts as a hydrogen-bond donor to the centroid, Cg3, of the C31—C36 ring of the silanol molecule at (x - 1/2, y - 1/2, z), so generating by translation a chain running parallel to the [110] direction (Fig. 5), while the action of a twofold rotation axis generates a similar chain parallel to [110]. These two chains are linked via the O—H···O hydrogen bonds to the DMSO, and propagation of the two interactions generates an (001) sheet lying in the domain 0 < z < 1/2. Adjacent sheets are linked by a second C—H···π(arene) interaction.

Atom C23 in the silanol molecule at (x, y, z) lies in the 0 < z < 1/2 sheet. This atom acts as a hydrogen-bond donor to the centroid, Cg1, of the C11—C16 ring in the silanol molecule at (-x, 1 - y, 1 - z) (Fig. 6), which is part of the sheet in the domain 1/2 < z < 1.0. The action of the twofold axes similarly links the 0 < z < 1/2 sheet to its neighbour in the domain -1/2 < z < 0, and hence all the sheets are linked into a single framework by the action of this centrosymmetric motif.

Crystallization of triphenylsilanol from 1,4-dioxan yields a 4:1 adduct, (Ph₃SiOH)₄·C₄H₈O₂, (III). The structure of this adduct has been reported using data collected at 293 K (Bourne, Johnson et al., 1991), and the supramolecular structure was discussed in terms of a finite centrosymmetric five-molecule aggregate. We have now re-investigated this compound at 150 (2) K, using a rather larger data set (6905 reflections, as opposed to 4435). The same phase clearly exists at the two temperatures, but careful examination of the structure refined from the 150 K data shows that the centrosymmetric aggregates (Fig. 7) are in fact linked by two C—H···π(arene) hydrogen bonds (Table 6), which co-operate to form molecular ladders along the [100] direction. Atoms C134 and C214 in the two silanol molecules at (x, y, z) act as hydrogen-bond donors to, respectively, the rings C111—C116 and C121—C126 in the type 1 silanol molecule at (x - 1, y, z) (Table 6; Fig. 8). The Si—O distances in (III) (Table 5) are intermediate between those in (I) and (II), while the Si—C distances are not significantly different from those in (I) and (II).

It is striking that crystallization of triphenylsilanol yields specific stoichiometric solvates when crystallized from DMSO or dioxan, but, when crystallized from acetone, which is expected to be at least as good an acceptor of hydrogen bonds as dioxan, the solvent-free phase (I) is formed. Likewise, it has been reported (Bourne, Nassimbeni et al., 1991) that crystallization of triphenylsilanol from mixtures of ethanol with any of methanol, propanol or water selectively yields a 4:1 ethanol solvate, (Ph₃SiOH)₄·(C₂H₆O). Clearly, the crystallization conditions which lead to formation of phases other than (I) are highly specific. It is also notable that no solvent-free polymorph of triphenylsilanol other than (I) has yet been observed, suggesting that this phase may be particularly stable, despite the absence from the structure of both C—H···π(arene) and π···π stacking interactions.

In summary, the hydroxyl H atoms in (Ph₃SiOH)₄ have been located at 120 (2) K, as for (Ph₃SnOH)_n (Glidewell et al., 2002), and the ring disorder is straightforwardly handled. At 198 K (Puff et al., 1991), the ring disorder appears to be more extensive, and at ambient temperature, the extensive disorder and the poor diffraction intensity effectively preclude a straightforward refinement. In the solvates (II) and (III), finite aggregates generated by O—H···O hydrogen bonds are further linked by C—H···π(arene) interactions.

S2. Experimental

A sample of triphenylsilanol was purchased from Aldrich. Crystals of (I), (II) and (III) suitable for single-crystal X-ray diffraction were grown by slow evaporation of solutions in the appropriate solvents. The same phase, (I), was obtained from solutions in acetone, chlorobenzene, chloroform, cyclohexane, dichloromethane, ethyl acetate, ethylbenzene, toluene and p-xylene.

S3. Refinement

Compound (I) is triclinic; space group P1 was selected, and confirmed by the subsequent analysis. At 120 (2) K, all H atoms were located from difference maps, and they were treating as riding atoms, with C—H = 0.95 Å; hydroxyl H atoms were treated as riding, using AFIX 3 (SHELXL97; Sheldrick, 1997) and with O—H = 0.88 Å, the mean of the eight values derived directly from the difference maps. One ring is disordered at 120 (2) K over two sets of sites, denoted C21r (r = 1 to 6) and C21N (N = A to F), occupying closely similar volumes of space. The rings were modelled as rigid hexagons and their site occupancy factors, when constrained to sum to 1, refined to 0.52 (4) and 0.48 (4); hence, the occupancies were thereafter fixed at 0.50 for both orientations. Compound (II) crystallized in the monoclinic system. The systematic absences permitted C2/c and Cc as possible space groups; C2/c was selected and confirmed by the analysis. The position of the hydroxyl H atom was obtained from a difference map, and all H atoms in the silanol component were treated as riding atoms, with C—H = 0.95 Å and O—H = 0.89 Å. The disordered DMSO molecule was modelled using the PART instruction in SHELXL97. The unique C atom was treated as two parts, with occupancies of 0.5 on a fixed common site, and the S atom was positioned in two symmetry-related sites. This was done to permit positioning of the H atoms of the methyl groups, which were treated as riding atoms with C—H = 0.98 Å. The partial C atoms were given common anisotropic displacement parameters, as were the S atoms. Compound (III) is triclinic; space group P1 was selected, and confirmed by the subsequent analysis. The H atoms were treated as riding, with C—H = 0.95 Å (aromatic) or 0.99 Å (CH₂), and O—H = 0.88 Å.

Special details

Experimental. The program DENZO-SMN (Otwinowski & Minor, 1997) uses a scalingalgorithm [Fox, G. C. & Holmes, K. C. (1966). Acta Cryst. 20, 886–891] which effectively corrects for absorption effects. High-redundancy data were used in the scaling program, hence the `multi-scan' code word was used.

Special details

Experimental. The program DENZO-SMN (Otwinowski & Minor, 1997) uses a scaling algorithm [Fox, G. C. & Holmes, K. C. (1966). Acta Cryst. 20, 886–891] which effectively corrects for absorption effects. High-redundancy data were used in the scaling program, hence the `multi-scan' code word was used.

Special details

Experimental. The program DENZO-SMN (Otwinowski & Minor, 1997) uses a scaling algorithm [Fox, G. C. & Holmes, K. C. (1966). Acta Cryst. 20, 886–891] which effectively corrects for absorption effects. High-redundancy data were used in the scaling program, hence the `multi-scan' code word was used.
