Abstract: The title compound, [CuCl₂(C₅H₁₀N₄)]_n, is the first structurally characterized complex of a transition metal halide with a 2-monosubstituted tetrazole. The Cu atom is five-coordinated and has a distorted square-pyramidal coordination geometry. One of the basal sites of the pyramid is occupied by an N atom of the tetrazole ligand [Cu-N = 2.0131 (19) Å]. A Cl atom occupies the apical position [Cu-Cl = 2.6438 (8) Å] and belongs to the basal plane of the coordination pyramid of the neighbouring Cu atom. In fact, all the Cl atoms act as bridging ligands and the Cu atom coordination polyhedron shares both Cl-Cl edges with the polyhedra of two neighbouring Cu atoms, thus giving rise to polymeric chains running along the a axis of the crystal.
