Benzylammonium chloride was prepared by the dropwise addition of concentrated hydrochloric acid (37%, Aldrich) to a solution of benzylamine (99%, Saarchem) in chloroform (99%, Saarchem). The precipitate was filtered and allowed to dry. The title compound was crystallized by slow evaporation of a methanol solution of SnCl2·H2O (96%, Saarchem) and benzylammonium chloride (stoichiometric ratio of 1:2) at room temperature. A plate-like colourless crystal of (I) was selected for the X-ray diffraction study.
All H atoms were placed in calculated positions, with C—H distances in the range 0.93–0.97 and N—H distances of 0.89 Å, and refined using a riding model, with Uiso(H) = 1.5Ueq(parent atom). Please check added text.

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. |

Due to their two-dimensional structure and interesting magnetic and electronic properties, organic-inorganic hybrid compounds of the formula (R—NH3)2SnX4 (where X is F, Cl, Br or I) have attracted a great deal of attention (Koutselas et al., 1996; Mitzi et al., 1998; Kagan et al., 1999; Raptopoulou et al., 2002). On the other hand, the structural characteristics of compounds with the formula (R—NH3)2SnX6 have not been investigated extensively. The crystal structures of only four primary n-alkylammonium hexachlorotin(IV) compounds, with chain lengths ranging from one to four, have been reported in the literature to date (Kitahama et al., 1979; Knop et al., 1983; Elleuch et al., 1996). No crystal structure of an arylammonium hexachlorotin(IV) compound has been reported previously. In this investigation, the crystal structure of bis(benzylammonium) hexachlorotin(IV), (I), was determined and the results are presented here. \sch
The molecular geometry and atom-numbering scheme used are shown in Fig. 1. The structure of (I) consists of alternating ionic and hydrocarbon layers. The hydrocarbon layer is comprised of benzyl moeties, and the ionic layer contains ammonium groups and SnCl62− octahedra.
In the hydrocarbon layer, the aromatic rings are interdigitated and tilted relative to the ionic layer. There are two crystallographically inequivalent benzylammonium cations in the asymmetric unit. For the two cations, the atoms constituting each of the aromatic rings are coplanar, with r.m.s. deviations of 0.003 and 0.007 Å. The angle between the planes through the aromatic rings is 24.2 (2)°. The two aromatic ring planes are tilted by angles of 68.27 (14) and 87.98 (15)° relative to the ionic layer. Intermolecular π–π interactions are evident, with a short centroid-to-centroid distance of 3.773 (4) Å.
In the ionic layer, extending parallel to the ab plane, isolated distorted SnCl62− octahedra interact with ammonium groups via hydrogen bonds. Unlike the (R—NH3)2SnX4 structures, the SnCl62− octahedra in (I) do not share corners.
The two ammonium groups in the asymmetric unit of (I) display different hydrogen-bonding interactions with Cl atoms. Atom N1 is hydrogen-bonded to five Cl atoms through four bifurcated and one normal hydrogen bond. Atom N2 is also hydrogen-bonded to five Cl atoms, but through two normal hydrogen bonds and one trifurcated hydrogen bond. Hydrogen-bonding donor-acceptor distances range from 3.282 (5) to 3.631 (5) Å. Sn—Cl bond lengths differ significantly (Table 1), and range from 2.1064 (14) to 2.4590 (12) Å. The Sn—Cl bond lengths for the Cl atoms engaged in strong hydrogen bonding, i.e. atoms Cl5 [N2—H2C···Cl5 3.282 (5) Å], Cl2 [N2—H2A···Cl2 3.357 (4) Å] and Cl6 [N1—H1A···Cl6 3.464 Å], are elongated. Additional hydrogen-bonding parameters are listed in Table 2. The SnCl62− octahedra are tilted relative to the ab plane, by an angle of 40.06 (4)°. In consecutive ionic layers, the octahedra have opposite tilt directions. The tilted octahedra and layered packing are illustrated in Fig. 2.
