title: catena-Poly[[bis(cis-1-tert-butyltetrazole-kappaN4)copper(II)]-di-micro-chloro].
abstract: The title polymeric compound, [CuCl(2)(C(5)H(10)N(4))(2)](n), is the first structurally characterized complex with a bulky 1-alkyltetrazole ligand. The coordination polyhedron of the Cu atom is an elongated octahedron. The equatorial positions of the octahedron are occupied by the two Cl atoms, with Cu-Cl distances of 2.2920 (8) and 2.2796 (9) A, and by the two N-4 atoms of the tetrazole ligands, with Cu-N distances of 2.023 (2) and 2.039 (2) A. Two symmetry-related Cl atoms occupy the axial positions, at distances of 2.8244 (8) and 3.0174 (8) A from the Cu atom. The [CuCl(2)(C(5)H(10)N(4))(2)] units form infinite chains extended along the b axis, linked together only by van der Waals interactions. The skeleton of each chain consists of Cu and Cl atoms.
