title: catena-Poly[[chloridocopper(II)]bis-(μ-3,3',5,5'-tetra-methyl-4,4'-methylene-dipyrazole)[chloridocopper(II)]-di-μ-chlorido].
abstract: In the title compound, [Cu(2)Cl(4)(C(11)H(16)N(4))](n), the Cu atom is coordinated by two N atoms of two 3,3',5,5'-tetra-methyl-4,4'-methyl-enedipyrazole (H(2)mbdpz) ligands, two bridging Cl atoms and one terminal Cl atom, forming a square-pyramidal geometry. The bridging Cl atoms and the bridging H(2)mbdpz ligands connect the Cu atoms to build up an extended one-dimensional chain. The chains are further connected through N-H⋯Cl hydrogen bonds to build up a two-dimensional layer in the (011) plane. An inversion centre lies between every pair of adjacent Cu atoms.
