Poly[bis­[chlorido­cop­per(I)]-μ4-1,4-bis­[1-(3-pyridylmeth­yl)-1H-benzimid­azol-2-yl]butane]

The title CuI coordination polymer, [Cu2Cl2(C30H28N6)]n, was obtained by reaction of CuCl2·2H2O and 1,4-bis­[1-(3-pyridyl­meth­yl)-1H-benzimidazol-2-yl]butane. Each CuI cation is three-coordinated by a ClN2 donor set. The anion acts as a tetra­dentate ligand, linking CuI centres into a polymeric chain
