Layered structure of catena-poly[[bis[1-(2-azidoethyl)tetrazole-N-4]copper(II)]-di-mu-chloro]

In the title compound, [CuCl2(C3H5N7)(2)], the coordination polyhedron of t he Cu atom is an elongated square bipyramid with (1) over bar site symmetry . The equatorial positions are occupied by the two Cl atoms with Cu-Cl dist ances of 2.288 (1) Angstrom and two azidoethyltetrazole ligands with Cu-N d istances of 1.999 (2) Angstrom. Two Cl atoms in axial positions are 2.956 ( 1) Angstrom distant from the Cu atom. The Cl atoms play the role of nonsymm etrical bridges responsible for formation of layers parallel to the bc plan e.
