A structural study of Si₆-ring-containing [Si₆Cl₁₄]²⁻ chloro­silicates

The crystal structures of four substituted-ammonium dichloride dodeca­chloro­hexa­silanes are presented. Each is crystallized with a different cation and one of the structures contains a benzene solvent mol­ecule: bis­(tetra­ethyl­ammonium) dichloride dodeca­chloro­hexa­silane, 2C₈H₂₀N⁺·2Cl⁻·Cl₁₂Si₆, (I), tetra­butyl­ammonium tri­butyl­methyl­ammonium dichloride dodeca­chloro­hexa­silane, C₁₆H₃₆N⁺·C₁₃H₃₀N⁺·2Cl⁻·Cl₁₂Si₆, (II), bis­(tetra­butyl­ammonium) di­chlo­ride dodeca­chloro­hexa­silane benzene disolvate, 2C₁₆H₃₆N⁺·2Cl⁻·Cl₁₂Si₆·2C₆H₆, (III), and bis­(benzyl­tri­phenyl­phospho­nium) dichloride dodeca­chloro­hexa­silane, 2C₂₅H₂₂P⁺·2Cl⁻·Cl₁₂Si₆, (IV). In all four structures, the dodeca­chloro­hexa­silane ring is located on a crystallographic centre of inversion. The geometry of the dichloride dodeca­chloro­hexa­silanes in the different structures is almost the same, irrespective of the cocrystallized cation and solvent. However, the crystal structure of the parent dodeca­chloro­hexa­silane mol­ecule shows that this mol­ecule adopts a chair conformation. In (IV), the P atom and the benzyl group of the cation are disordered over two sites, with a site-occupation factor of 0.560 (5) for the major-occupied site.

S1. Introduction

Thin films of nanocrystalline, microcrystalline and amorphous silicon (Si) are and will be an important element of present and future semiconductors. Until today, such Si films are made through gas-phase deposition of smaller silanes. Those silanes are obtained from the reduction of the corresponding chloro­silanes. A promising approach to improve the manufacturing of Si films are solution-based methods, such as spin, spray or printing processes. Therefore, higher oligosilanes with boiling points significantly higher than their deposition temperatures are in demand. It is expected that silanes consisting of ten or more Si atoms meet those requirements best. Known synthetic routes are much too laborious and expensive to be used in large-scale production, it is a necessity to develop synthesis strategies that give easy access to precursor oligo­chloro­silanes. The amine-induced disproportionation of Si₂Cl₆ leading to Si(SiCl₃)₄ and SiCl₄ has been known for years (Urry, 1970; Meyer-Wegner et al., 2011). Recently, we have established convenient access to chloro­silicates of the type [Si₆Cl₁₄]^2-, [Si₇Cl₁₆]^2- and [Si₈Cl₁₈]^2- by chloride-induced disproportionation of Si₂Cl₆ (Tillmann et al., 2012, 2014). The Si₆ rings of the chloro­silicate are coordinated at both faces by chloride ions and therefore show an inverse sandwich structure. This structural motif was first described by Choi et al. (2001).

In this context, it should be noted that chloro­silicates can be easily transformed into the corresponding silanes by treatment of these compounds with LiAlH₄.

In the course of our investigations, we have prepared a series of complexes, namely [Et₄N]₂Cl₂[Si₆Cl₁₄], (I), [nBu₄N][nBu₃MeN]Cl₂[Si₆Cl₁₄], (II), [nBu₄N]₂Cl₂[Si₆Cl₁₄].2C₆H₆, (III), and [Ph₃BnP]₂Cl₂[Si₆Cl₁₄], (IV), the crystal structures of which we report here.

S2. Experimental

S2.1. Synthesis and crystallization

Synthesis of the chloro­silicates [Et₄N]₂[Si₆Cl₁₄], (I), [nBu₄N][nBu₃MeN][Si₆Cl₁₄], (II), [nBu₄N]₂[Si₆Cl₁₄] . 2C₆H₆, (III), [Ph₃BnP]₂[Si₆Cl₁₄], (IV):

Si₂Cl₆ [0.3 ml, 1.7 mmol for (I); 0.5 ml, 2.9 mmol for (II); 0.3 ml, 1.7 mmol for (IV)] was added to solutions of the related ammonium or phospho­nium chloride, namely [Et₄N]Cl (92 mg, 0.6 mmol) for (I), [nBu₄N]Cl (100 mg, 0.4 mmol) along with nBu₃N {the ammonium salt [nBu₃MeN]Cl is formed from nBu₃N and two molecules of CH₂Cl₂ (Tillmann et al., 2012)} (60 mg, 0.3 mmol) for (II), and [Ph₃BnP]Cl (220 mg, 0.6 mmol) for (IV), all in CH₂Cl₂ (0.3–0.5 ml). When the reaction mixtures were allowed to stand at room temperature, single crystals of the Si₆-ring containing chloro­silicates [Si₆Cl₁₄]^2- grew after a few days. The crystalline yields were (I) < 15%, (II) < 20% and (IV) 40%. In addition, the chloro­silicates [(Cl₃Si)Si₆Cl₁₃]^2-, [1,1-(Cl₃Si)₂Si₆Cl₁₂]^2- and [1,4-(Cl₃Si)₂Si₆Cl₁₂]^2- were obtained as side products of these reactions. Single crystals of (III) were grown from a cooled (279 K) solution of [nBu₄N]₂[Si₆Cl₁₄] (10 mg) after one week.

S2.2. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 1. The H atoms in all structures 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 H atoms or 1.2U_eq(C) otherwise.

The P atom and the benzyl group of the phospho­nium cation of (IV) are disordered over two sites with a site-occupation factor of 0.560 (5) for the major-occupied site. The C1'—C41 bond was restrained to 1.540 (5) Å. The disordered C atoms were refined isotropically.

S3. Results and discussion

\ Bis(tetra­ethyl­ammonium) dichloride dodeca­chloro­hexasilane, (I) (Fig. 1), crystallizes with discrete cations, anions and half a molecule of dodeca­chloro­hexasilane, which is located on a centre of inversion, in the asymmetric unit. The crystal packing diagram (Fig. 2) shows the arrangement of alternating cations and anions in the unit cell. The hexasilane ring is exactly planar and the two chloride anions are located almost exactly over the centre of the hexasilane ring (cog) (Table 2). The nonbonding Cl···Si distances range from 2.9471(10 (Cl1···Si2) to 3.0285 (10) Å [Cl1···Si1ⁱ; symmetry code: (i) -x+1, -y+1, -z+1].

Tetra­butyl­ammonium tri­butyl­methyl­ammonium dichloride dodeca­chloro­hexasilane, (Figs. 3, 4, 5 and 6), (II), crystallizes with two cations, two anions and two half molecules of dodeca­chloro­hexasilane, which are both located on a centre of inversion, in the asymmetric unit. The hexasilane ring is almost planar and the two chloride anions are located almost exactly over the centre of the hexasilane ring (Table 2). The Cl···Si distances range from 2.9473 (16) [Cl1···Si3ⁱ; symmetry code: (i) -x+1, -y+1, -z] to 3.0837 (16)Å (Si2···Cl1) and from 2.9896 (14) [Cl2···Si5ⁱⁱ; symmetry code: (ii) -x, -y+2, -z+1] to 3.0483 (14) Å [Cl2···Si4ⁱⁱ; symmetry code: (ii) -x, -y+2, -z+1]. The crystal packing (Fig. 7,) shows how the anions and cations are neatly separated.

Bis(tetra­butyl­ammonium) dichloride dodeca­chloro­hexasilane di­benzene solvate, (III) (Figs. 8 and 9) crystallizes with one cation, one anion, half a molecule of dodeca­chloro­hexasilane, which is located on a centre of inversion, and one benzene molecule in the asymmetric unit. The hexasilane ring is essentially planar and the two chloride anions are located almost exactly over the centre of the hexasilane ring (Table 2). The Cl1···Si distances range from 2.9618 (13) [Cl1···Si1ⁱ; symmetry code: (i) -x+1, -y+1, -z+1] to 3.0355 (12) Å (Cl1···Si2). The crystal packing diagram (Fig. 10) shows how the benzene solvent molecule is surrounded by the butyl chains of two cations.

Bis(benzyl­tri­phenyl­phospho­nium) dichloride dodeca­chloro­hexasilane, (IV) (Figs. 11 and 12), crystallizes with one cation, one anion and half a molecule of dodeca­chloro­hexasilane, which is located on a centre of inversion, in the asymmetric unit. The hexasilane ring is almost planar and the two chloride anions are located almost exactly over the centre of the hexasilane ring (Table 2). The Cl···Si distances range from 2.967 (2) [Cl1···Si2ⁱ; symmetry code: (i) -x+1, -y+2, -z] to 3.051 (2) Å (Cl1···Si3ⁱ). The packing diagram (Fig. 13) shows the arrangement of the different entities in the unit cell. Anions and cations are once again neatly separated.

A search in the Cambridge Structural Database (CSD, Version 3.5, with three updates; Groom & Allen, 2014) for the dichloride dodeca­chloro­hexasilane fragment yielded only 2 hits, namely bis­[2-(di­methyl­amino)-N,N,N-tri­methyl­ethanaminium] dichloride dodeca­chloro­hexasilane (CSD refcode LECXIC; Tillmann et al., 2012) and bis­[(N,N,N',N",N"-\ penta­ethyl­diethylenetri­amine-κ³N,N',N")\ chloridodihydridosilicon] dodeca­chloro­cyclo­hexasilane dichloride (NENLOH; Choi et al., 2001). Table 2 lists the most important geometric parameters of the dichloride dodeca­chloro­hexasilane fragments in all six structures. The six-membered ring is planar throughout all structures. The average Si—Si bond length and average Si—Cl bond length are almost identical in all structures. The Cl···Cg distance is also essentially the same in all structures. Only the distance from the Cl anion to the centre of the Si₆ ring shows minor deviations. As a result, it can be stated that the geometric parameters of the dichloride dodeca­chloro­hexasilane fragment is almost invariable. It does not change if it is crystallized with a different anion or solvent.

It is of inter­est to note that the the dichloride dodeca­chloro­hexasilane fragment shows the tendency to crystallize on a crystallographic centre of inversion. The only exception is the structure NENLOH with a complete Cl₁₂Si₆.2Cl^- fragment in the asymmetric unit.

If dodeca­chloro­hexasilane is crystallized with two iodide anions (Dai et al., 2011), the resulting structure, namely bis­(tetra­butyl­ammonium) dodeca­chloro­hexasilane bis­(iodide) di­chloro­methane solvate, shows the same features as the already discussed structures: the six-membered ring is essentially planar (r.m.s. deviation = 0.023Å), the average Si—Si bond is 2.337 (9) Å and the average Si—Cl bond is 2.084 (8) Å. In accordance with the increased size of a iodide anion compared with a chloride anion, the average Si···I distance is increased to 3.29 (3) Å and the distance from the iodide anions to the centre of the ring is 2.328 Å for I1 and 2.304 Å for I2.

If dodeca­chloro­hexasilane is crystallized for itself without any additional ion or solvent, the hexasilane ring is no longer planar but adopts a chair conformation (Dai et al., 2011). In this compound, the average Si—Si bond is slightly longer [2.342 (4) Å] and the average Si—Cl bond is significantly shortened [2.029 (4) Å].

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.

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.

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.

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.
