The structure of the title compound, cis-[PtCl2(C2H5N5)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 C2 symmetry. Inter­molecular N—H...Cl hydrogen bonds mediate the formation of a three-dimensional supra­molecular network.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles
