Crystal structure of bis(diisopropylammonium) cis-diiodidobis (oxolato-κ2O1, O2)stannate (IV)

In the title compound, ((Pr2NH2)-Pr-i)(2)[SnI2(C2O4)(2)], which was prepared by reacting ((Pr2NH2+)-Pr-i)(2)center dot C2O42- with SnI4 in a 2:1 molar ratio in a mixed ethanol-acetonitrile solvent, the Sn atom is coordinated by two chelating oxalate ions and two iodide ions, with the latter in a cis configuration. In the crystal, the cations are linked to the anions by N-H center dot center dot center dot O and bifurcated N-H center dot center dot center dot(O, O) hydrogen bonds, generating [10 (1) over bar] chains.
