An X-ray powder diffraction study of cis-dichloridobis(2-methyl-2H-tetrazol-5-amine-κN⁴)platinum(II), a tetrazole-containing analogue of cisplatin

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.
