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

Abstract

In the title compound, (iPr2NH2)2[SnI2(C2O4)2], which was prepared by reacting (iPr2NH2+)2·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...O and bifurcated N—H...(O,O) hydrogen bonds, generating [10-1] chains.
