Reaction of oxalic acid and diphenyltin dichloride in the presence of cyclohexylamine led to the formation of the title salt, (C6H14N)2[Sn(C6H5)2(C2O4)2]. The dianion is made up from an Sn(C6H5)2 moiety cis-coordinated by two chelating oxalate anions, leading to an overall distorted octahedral coordination geometry of the SnIV atom. The negative charges are compensated by two surrounding cyclohexylammonium cations adopting chair conformations each. In the crystal, anions and cations are linked via a network of N—H⋯O hydrogen bonds into a layered arrangement parallel to (101).
Keywords: crystal structure; organotin(IV) compound; oxalate ligands; cis arrangement; cyclohexylammonium; N—H⋯O hydrogen bonding.

1. Chemical context
Organotin(IV) complexes are particularly investigated for their catalytic applications as well as for their potential biocidal properties (Davies et al., 2008). Thus, numerous studies have been carried out in order to determine the biological properties of organotin(IV) compounds against bacteria, fungi or cancer cell lines (Gielen, 2002). In this context, and in the course of our ongoing studies on organotin(IV) chemistry (Gueye et al., 1993; Kane et al., 2009; Fall, Okio et al., 2010; Fall, Sow et al., 2010), we have isolated the title stannate as colourless crystals from the reaction of oxalic acid and diphenyltin dichloride in the presence of cyclohexylamine. To date, several organotin(IV) oxalates have been characterized by X-ray crystallographic analysis showing cis- and trans-coordination of the oxalate anion, depending on the nature of the σ-bonded carbon ligand that is linked to SnIV (Ng, 1996, 1999; Ng et al., 1992; Ng & Hook, 1999; Ng & Rae, 2000; Xu et al., 2003a,b; Gueye et al., 2010, 2012; Reichelt & Reuter, 2014).
2. Structural comment
In the title salt, 2(C6H14N)+[Sn(C6H5)2(C2O4)2]2− or 2(CyNH3)+[Sn(Ph2)(C2O4)2]2− (Cy is cyclohexyl; Ph is phenyl), the SnPh2 moiety is chelated by two oxalate anions, leading to a cis arrangement within the distorted octahedral coordination sphere of the SnIV atom. The Sn—C distances and angles of the SnPh2 moiety [Sn—C5 = 2.1388 (15) Å, Sn—C11 = 2.1486 (15) Å with a C5—Sn—C11 angle of 106.94 (6)°] are similar to those previously reported for analogous diphenyltin(IV) derivatives (Xu et al., 2003a,b; Ng & Rae, 2000). The of both oxalate anions is relatively symmetrical [Sn—O1 = 2.2005 (10) Å and Sn—O3 2.1267 (10) Å; Sn—O5 2.1883 (10) Å and Sn—O7 2.1396 (10) Å]. However, the oxalate anions are slightly distorted with O1—C1—C2—O3 and O5—C3—C4—O7 torsion angles of −4.0 (2) and −9.98 (19)°, respectively. They form a dihedral angle of 77.40 (8)° between their least-squares planes. The molecular structure of the title compound, showing the atom-numbering scheme, is depicted in Fig. 1.
3. Supramolecular features
From a supramolecular point of view, anions and cations of the title salt exhibit intermolecular interactions through N—H⋯O hydrogen-bonding contacts. Both coordinating and non-coordinating oxygen atoms of both oxalate anions are involved in these interactions (Table 1). Compared to the related structures of bis(diisopropylammonium) [diphenyldioxalatostannates(IV)] (Xu et al., 2003a,b) where the supramolecular arrangement defines infinite zigzag chains, the cyclohexylammonium cations in the title structure lead to a layer-like arrangement parallel to (101) (Fig. 2).
4. Synthesis and crystallization
Chemicals were purchased from Sigma–Aldrich, and used without further purification. The title compound was obtained by reacting [(CyNH3)2C2O4]·1.5H2O – obtained previously in crystalline form by mixing CyNH2 with oxalic acid (C2O4H2) in a 2:1 molar ratio in water and evaporation at 333 K – with SnPh2Cl2 in methanol (molar ratio 2:1). Colourless single crystals suitable for X-ray were obtained by slow solvent evaporation at room temperature.
5. Refinement
Crystal data, data collection and structure . The H atoms bonded to C or N atoms were placed at calculated positions using a riding model with C—H = 0.95 (aromatic), 0.99 (methylene) or N—H = 0.91 Å (amine) and with Uiso(H) = 1.2Ueq(C or 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. |
