Crystal structure of bis­(cyclo­hexyl­ammonium) di­phenyl­dioxalatostannate(IV)

Reaction of oxalic acid and di­phenyl­tin dichloride in the presence of cyclo­hexyl­amine led to the formation of the title salt, (C(6)H(14)N)(2)[Sn(C(6)H(5))(2)(C(2)O(4))(2)]. The dianion is made up from an Sn(C(6)H(5))(2) moiety cis-coordinated by two chelating oxalate anions, leading to an overall distorted octa­hedral coordination geometry of the Sn(IV) 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).
