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.
