catena-Poly[[chloridocopper(I)]-μ-η,σ-3-(2-allyl-2H-tetra-zol-5-yl)pyridine].

The title compound, CuCl(C(9)H(9)N(5)), prepared by solvo-thermal synthesis, is a new homometallic Cu(I)-olefin coordination polymer in which the Cu(I) atoms are linked by the 3-(2-allyl-2H-tetra-zol-5-yl)pyridine ligands and are each bonded to one terminal Cl atom. The organic ligand acts as a bidentate ligand bridging two neighboring Cu centers through the bonds to the N atom of the pyridine ring and the double bond of the allyl group. Weak Cu⋯Cl [3.136 (8) Å), C-H⋯Cl and C-H⋯N inter-actions connect the coordination polymers into a three-dimensional structure.
