Abstract

We have determined the crystal structures of two deca-chloro-cyclo-penta-silanes, namely bis-(tetra-n-butyl-ammonium) dichloride deca-chloro-cyclo-penta-silane di-chloro-methane disolvate, 2C16H36N+·2Cl-·Si5Cl10·2CH2Cl2, (I), and bis-(tetra-ethyl-ammonium) dichloride deca-chloro-cyclo-penta-silane di-chloro-methane disolvate, 2C8H20N+·2Cl-·Si5Cl10·2CH2Cl2, (II), both of which crystallize with discrete cations, anions, and solvent mol-ecules. In (I), the complete deca-chloro-cyclo-penta-silane ring is generated by a crystallographic twofold rotation axis. In (II), one cation is located on a general position and the other two are disordered about centres of inversion. These are the first structures featuring the structural motif of a five-membered cyclo-penta-silane ring coordinated from both sides by a chloride ion. The extended structures of (I) and (II) feature numerous C-H⋯Cl inter-actions. In (II), the N atoms are located on centres of inversion and as a result, the ethyl-ene chains are disordered over equally occupied orientations.

Chemical context

The title compounds are the first known halide diadducts of the long-known perchlorinated cyclo­penta­silane Si5Cl10 (Hengge & Kovar, 1977 ▸). Their structures can be seen as inverse-sandwich complexes, in which two chloride ions lie above and below the planar five-membered silicon ring. In the recent years, new and facile synthetic protocols for the Cl− diadduct [Si6Cl14]2– of dodeca­chloro­cyclo­hexa­silane have been developed. It can either be prepared through the chloride-induced disproportionation of Si2Cl6, which leads directly to [Si6Cl14]2– (Tillmann et al., 2012 ▸, 2014 ▸; Tillmann, Moxter et al., 2015 ▸), or the Lewis acidic uncomplexed Si6Cl12 can be used as the starting material. In the latter case, mere addition of soluble chloride salts [R 4N]Cl (R = nBu or Et) leads to the formation of [Si6Cl14]2– (Dai et al., 2010 ▸). Given this background, it was of inter­est to investigate the Lewis acidity and ability of Si5Cl10 to bind Cl− ions.

Structural commentary

Bis(tetra-n-butyl­ammonium) dichloride deca­chloro­cyclo­penta­silane di­chloro­methane disolvate, 2C16H36N+·2Cl−·Si5Cl10·2CH2Cl2, (I), crystallizes with discrete cations, anions, and solvent mol­ecules (Fig. 1 ▸). The five-membered deca­chloro­cyclo­penta­silane ring is located on a twofold rotation axis. The Si—Cl bond lengths range from 2.081 (3) Å for Si2—Cl21 to 2.100 (3) Å for Si2—Cl22. The Si—Si bond lengths do not vary markedly: they range from 2.339 (3) Å (Si1—Si2) to 2.347 (3) Å (Si2—Si3).

The almost planar ring (r.m.s. deviation 0.002 Å) is coord­inated by two chloride anions located above and below the ring. The distances of the chloride ions to the Si atoms [Cl1⋯Si1 2.907 (3), Cl1⋯Si2 2.914 (3), Cl1⋯Si3 2.930 (3) Å,] show that the chloride ions are located almost exactly above the centroid of the ring [distance Cl1⋯Cg = 2.1434 (16) Å]. Bis(tetra­ethyl­ammonium) dichloride deca­chloro­cyclo­penta­silane di­chloro­methane disolvate, 2C8H20N+·2Cl−·Si5Cl10·2CH2Cl2, (II), crystallizes as (I) with discrete cations, anions, and solvent mol­ecules (Fig. 2 ▸). The Si—Cl bonds again lie in a quite narrow range [2.0805 (9) Å (Si1—Cl12) to 2.1102 (8) Å (Si2—Cl22)] and the Si—Si bond lengths are also very similar [2.3386 (8) Å (Si1—Si2) to 2.3473 (7) Å (Si4—Si5)].

The five-membered deca­chloro­cyclo­penta­silane ring is almost planar (r.m.s. deviation = 0.017 Å) and coordinated by two chloride anions located above and below the ring with a Cl⋯Cg distance of 2.1781 (5) Å for Cl1 and 2.1237 (5) Å for Cl2. The Cl⋯Si distances range from 2.9381 (7) Å (Cl1⋯Si5) to 2.9645 (7) Å (Cl1⋯Si2) and from 2.8759 (8) Å (Cl2⋯Si2) to 2.9510 (7) Å (Cl2⋯Si5). Since the Cl⋯Si distances have a broader range for Cl2, it can be said that this ion is slightly displaced from a position directly over the ring centroid. It is inter­esting to note that (I) and (II) have – apart from the different cations – the same mol­ecular stoichiometry, i.e. one Si5Cl10 ring coordinated by two chloride anions, two cations and two solvent di­chloro­methane mol­ecules. However, since (I) has twofold rotation symmetry, there are only half of the chemical entities in the asymmetric unit.

Supra­molecular features

The components of (I) and (II) are linked by a plethora of C—H⋯Cl contacts (Tables 1 ▸ and 2 ▸, respectively); in particular the chloride ions are surrounded by C—H groups. For an example, see Fig. 3 ▸. As a result of the disorder of the N2 and N3 cations in (II), a plot showing the coordination of the Cl ions looks extremely crowded and is therefore omitted.

Database survey

The present structures are the first examples of a deca­chloro­cyclo­penta­silane ring coordinated by two anions. There are only two structures of a deca­chloro­cyclo­penta­silane ring in the CSD (Version 5.38 of November 2016 plus three updates; Groom et al., 2016 ▸), namely deca­chloro­cyclo­penta­silane 4-methyl­benzo­nitrile solvate (refcode ELAFON; Dai et al., 2010 ▸) and deca­chloro­cyclo­penta­silane aceto­nitrile solvate (ELAFIH; Dai et al., 2010 ▸). In both of them, the deca­chloro­cyclo­penta­silane ring is almost planar (0.017 Å for ELAFON and 0.001 Å for ELAFIH) and shows almost no variation in the Si—Si (2.358–2.368 Å for ELAFON and 2.342–2.349 Å for ELAFIH) and Si—Cl (2.030–2.059 Å for ELAFON and 2.034– 2.038 Å for ELAFIH) bond lengths. The distance of the N atom to the centroid of the ring is 2.152 and 2.196 Å for ELAFON and 2.234 Å for ELAFIH. This difference could be due to the steric demand of the benzene ring in ELAFIH. The N⋯Cg distances are in the same range as the Cl⋯Cg distances in (I) and (II). Mean values of the structural parameters of the four compared structures and dichloride dodeca­chloro­cyclo­hexa­silanes (Tillmann, Lerner & Bolte, 2015 ▸) are compiled in Table 3 ▸. It is remarkable that the Si—Si and Si—Cl bond lengths do not vary significantly between the five and six-membered Si rings, but the Cl⋯Cg distance in the dodeca­chloro­cyclo­hexa­silanes is significantly shorter than for deca­chloro­cyclo­penta­silane. This might be due to the fact that the Cl ligands form a narrower cone in five- compared to six-membered rings.

Synthesis and crystallization

The addition of a solution of [R 4N]Cl (R = nBu or Et) in CH2Cl2 at 195 K to a solution of Si5Cl10 in CH2Cl2 furnished the Cl− diadducts [R 4N]2[Si5Cl12] (R = nBu or Et) (Fig. 4 ▸). Crystals of [R 4N]2[Si5Cl12] (R = nBu or Et) could be harvested after storage of the reaction solution for one week at 195 K in 89% and 93% yield, respectively. Both adducts are stable in the solid phase under inert conditions. However, in solution a rapid transformation of [nBu4N]2[Si5Cl12] to [nBu4N]2[Si6Cl14] and [nBu4N]2[Si7Cl16] (Fig. 5 ▸) can be observed via 29Si NMR spectroscopy (for the NMR spectrum see Fig. S1 in the Supporting information), while [Et4N]2[Si5Cl12] is not soluble. For comparison, a 29Si CP/MAS NMR spectrum of single crystals of [nBu4N]2[Si5Cl12] was recorded (Fig. S2 in the Supporting information).

The Cl atoms of the di­chloro­methane solvent mol­ecule in (I) have rather large displacement ellipsoids, but since no valid disorder model for splitting this mol­ecule could be found, refinement with enlarged ADPs was preferred. In (II), atoms N2 and N3 are located on centres of inversion. As a result, the ethyl­ene chains are disordered over equally occupied orientations.

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.

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.
