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.
利用室温下的内部X射线粉末衍射数据对标题化合物顺式-[PtCl₂(C₂H₅N₅)₂]的结构进行了分析。结构通过直接法求解并使用Rietveld分析进行精修。两个氯原子和2-甲基-2H-四唑-5-胺配体的两个环氮原子在铂原子周围形成了略微扭曲的平面正方形配位几何结构，它们呈顺式构型。四唑环的平面相对于配位平面倾斜79.7(7)°和73.8(6)°，其取代基的取向使得整个配合物具有近似C₂对称性。分子间的N-H···Cl氢键介导了三维超分子网络的形成。
