Bottom Line: Reaction of oxalic acid and di-phenyl-tin dichloride in the presence of cyclo-hexyl-amine 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 octa-hedral coordination geometry of the Sn(IV) atom.The negative charges are compensated by two surrounding cyclo-hexyl-ammonium cations adopting chair conformations each.

ABSTRACT
Reaction of oxalic acid and di-phenyl-tin dichloride in the presence of cyclo-hexyl-amine 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 octa-hedral coordination geometry of the Sn(IV) atom. The negative charges are compensated by two surrounding cyclo-hexyl-ammonium 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).

Crystal packing of the title compound, viewed approximately along the b axis, showing the layer-like arrangement parallel (101) via hydrogen-bonding inter­actions (dashed orange lines). H atoms not involved in hydrogen bonding have been omitted for clarity. Colour code: Sn = light blue, C = dark grey, H = white, N = dark blue and O = red.

H atoms not involved in hydrogen bonding have been omitted for clarity. Colour code: Sn = light blue, C = dark grey, H = white, N = dark blue and O = red.

Mentions: 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 ▸).
