TRANS-DICHLOROBIS(1-ETHYLTETRAZOLE-N-4)COPPER(II)

In the title compound, [CUCl2(C3H6N4)(2)], the tetrazole ligand is coo rdinated terminally by the N4 ring atom. The coordination polyhedron o f the Cu atom takes the form of an elongated square bipyramid with 1 s ite symmetry. The equatorial positions are occupied by two Cl atoms [C u-Cl 2.290(1) Angstrom] and two ethyltetrazole ligands [Cu-N 1.990(4) Angstrom]. In addition, there are two Cl atoms in axial positions [Cu- Cl 2.993(1) Angstrom]. Hence, the Cl atoms play the role of non-symmet rical bridges and connect the molecules into infinite layers located i n the yz plane.
