(Received 2 July 2013; accepted 12 July 2013; online 27 July 2013)

The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N+·C2O42−·1.5H2O and SnCl2·2H2O. The cyclo­hexyl­ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa­hedral coordination sphere of the SnIV atom with the O atoms in equatorial cis positions. In the crystal, cations and anions are linked through N—H⋯O and N—H⋯Cl inter­actions into a layered arrangement parallel to (100).

Comment top

Various applications of organotin(IV) compounds exist in many fields, e.g. related to agriculture, medicine, anti-fouling paints and wood preservatives (Evans & Karpel, 1985). Therefore new organotin compounds have been the research subject of many groups (Ballmann et al., 2009; Meriem et al., 1989; Ng & Kumar Das, 1997; Zhang et al., 2006). Our group has previously reported several halogenidotin(IV) derivatives (Diallo et al., 2009; Qamar-Kane & Diop, 2010). In this work, we report the results of the reaction between (C6H14N)2(C2O4).1.5H2O with SnCl2.2H2O leading to the formation of the title compound, (C6H14N)2[Sn(C2O4)Cl4], (I).

The asymmetric unit of (I) consists of an oxalate anion chelating a SnCl4 moiety (Fig. 1). The C—O distances in the oxalate anion [C1—O3 = 1.227 (4) Å; C2—O4 = 1.217 (4) Å; C1—O1 = 1.286 (4) Å; C2—O2 = 1.290 (4) Å] indicate double and single bonds, respectively. The Sn—O distances [Sn1—O1 = 2.155 (2) Å; Sn1—O2 = 2.121 (2) Å] and the Sn—Cl distances [Sn1—Cl1 = 2.3794 (9) Å; Sn1—Cl2 = 2.3667 (9) Å, Sn1—Cl3 = 2.3547 (9) Å and Sn1—Cl4 = 2.4407 (8) Å] (Table 1) are in good agreement with those of previously reported Sn—O and Sn—Cl bonds of related compounds (Willey et al.,1998; Skapski et al., 1974; Sow et al., 2010, 2013). The coordination sphere around the SnIV atom can be described as a slightly distorted octahedron with the O atoms of the oxalate ligand occupying equatorial cis-positions. The greatest deviation from the ideal octahedral geometry is manifested in the contraction of the Cl2—Sn1—Cl4 angle to 171.25 (3) °.

The stannate(IV) anion interacts with the two distinct cyclohexylammonium cations (both with chair conformation) through N—H···O and N—H···Cl hydrogen bonds (Table 2), leading to a two-dimensional network extending parallel to (100) (Fig. 2).

Experimental top

Chemicals were purchased from Sigma-Aldrich, and used without further purification. The title compound was obtained by reacting (C6H14N)2(C2O4).1.5H2O (0.09 g, 0.286 mmol) with SnCl2.2H2O (0,20 g, 0.890 mmol) in 25 ml of ethanol (96%). After slow solvent evaporation of the solvent at room temperature, colourless crystals suitable for X-ray diffraction analysis were obtained.

Refinement top

All H atoms, on carbon and nitrogen atoms, were placed at calculated positions using a riding model with C—H = 0.97 Å (methylene) or 0.98 Å (methine) and N—H = 0.89 Å with Uiso(H) = 1.2Ueq(C) and Uiso(H) = 1.5Ueq(N).

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.
