catena-Poly[[chloridocopper(I)]-μ-η(2),σ(1)-3-(2-allyl-2H-tetra­zol-5-yl)pyridine]

The title compound, [CuCl(C(9)H(9)N(5))](n), prepared by solvo­thermal synthesis, is a new homometallic Cu(I)–olefin coordination polymer in which the Cu(I) atoms are linked by the 3-(2-allyl-2H-tetra­zol-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 inter­actions connect the coordination polymers into a three-dimensional structure.
