Bis(dicyclohexylammonium) μ-oxalato-κ4O1,O2:O1′,O2′-bis[aqua(oxalato-κ2O1,O2)diphenylstannate(IV)]

Abstract

The structure of the title compound, (C12H24N)2[Sn2(C6H5)4(C2O4)3(H2O)2], consists of a bischelating oxalate ion, located on an inversion center, which is linked to two SnPh2 groups. The coordination sphere of the Sn(IV) ion is completed by a monochelating oxalate anion and a water molecule. The Sn(IV) atoms are thus seven-coordinated. The discrete binuclear units are further connected by hydrogen bonds, leading to a supramolecular crystal structure. The asymmetric unit contains one half dianion and one (Cy2NH2)+ cation.
