The data on synthesis, crystal structure, magnetic susceptibility and thermal properties of coordination compound of copper(II) chloride with 2-methyltetrazole (2mtet) of Cu(2mtet)2Cl2 composition are reported. The Cu atom environment forms an elongated octahedron, with two 2-methyltetrazole ligands (N4 bound) and two Cl atoms in the equatorial positions. Symmetry related 2-methyltetrazole ligand and Cl atom are in the axial positions. One of the two 2-methyltetrazole molecules of the asymmetric unit exhibits bridging properties being linked to two Cu atoms through two N atoms (i.e., N4 and N1) of the tetrazole ring, while the other ligand molecule is coordinated in monodentate fashion via one tetrazole N4 atom. The Cu-octahedra form dinuclear building bricks by sharing edges with equatorial and axial Cl atoms. These dinuclear units are linked together via bridging 2-methyltetrazole ligands to form infinite layers parallel to the (101¯) plane. Magnetic properties of Cu(2mtet)2Cl2 and the data of quantum-chemical calculations of molecular electrostatic potential and energies of hydronation of nitrogen atoms for 2mtet using B3LYP/6-31G* level of theory are in agreement with the structural data obtained.
