Crystal structure of bis(cyclohexylammonium) diphenyldioxalatostannate(IV)

Abstract

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).
