Abstract: In the title compound, [Cu₂Cl₄(C₁₁H₁₆N₄)]_n, the Cu atom is coordinated by two N atoms of two 3,3',5,5'-tetramethyl-4,4'-methylenedipyrazole (H₂mbdpz) ligands, two bridging Cl atoms and one terminal Cl atom, forming a square-pyramidal geometry. The bridging Cl atoms and the bridging H₂mbdpz ligands connect the Cu atoms to build up an extended one-dimensional chain. The chains are further connected through N-HCl hydrogen bonds to build up a two-dimensional layer in the (011) plane. An inversion centre lies between every pair of adjacent Cu atoms.
