Abstract

The structure of the title compound, cis-[PtCl(2)(C(2)H(5)N(5))(2)], was analysed using in-house X-ray powder diffraction data at room temperature. The structure was solved by direct methods and refined using Rietveld analysis. A slightly distorted square-planar coordination geometry is formed around the Pt atom by two Cl atoms and two ring N atoms of the 2-methyl-2H-tetrazol-5-amine ligands, which are in a cis configuration. The planes of the tetrazole rings are inclined at 79.7 (7) and 73.8 (6)° with respect to the coordination plane, with their substituents oriented in such a way that the complex as a whole has approximate C(2) symmetry. Intermolecular N-H···Cl hydrogen bonds mediate the formation of a three-dimensional supramolecular network.
