cis-Amminedichloroisopropylamineplatinum(II) by X-ray powder diffraction analysis

The title compound, [PtCl2(C3H9N)(NH3)], was obtained from potassium tetrachloroplatinate(II) by a two-step route. Ab initio crystal structure determination was carried out using X-ray powder diffraction techniques. Patterson and Fourier syntheses were used for the atom locations and the Rietveld technique for the final structure refinement. The Pt coordination is close to planar, with Cl atoms in a cis orientation. Molecules are combined into groups of two molecules, with antiparallel PtN2Cl2 planes and a shortest Pt...Pt distance of 3.42 angstroms. The molecule groups are packed in a parquet motif into corrugated layers parallel to ab. The molecules in the layers are linked by H-N...Cl hydrogen bonds.
