Abstract

The central CuII atom of the molecular title complex, [CuCl2(C2H3N3)4], is situated on a site with symmetry 2.22. It is six-coordinated in an elongated octa­hedral geometry, with the equatorial plane defined by four N atoms of four 1,2,4-triazole ligands and the axial positions occupied by two Cl atoms situated on a twofold axis. The mol­ecules are connected via N—H⋯Cl hydrogen bonds and the crystal consists of two inter­penetrating three-dimensional hydrogen-bonded frameworks.
