In the title compound, [CuCl2(C26H18N4)]n, the Cu(II) ion is four-coordinated by two N atoms from two 4,4′-bis(benzoimidazol-1-yl)biphenyl ligands and two chloride anions, in a slightly distorted tetrahedral environment. The biphenyl ligand acts as a linear bidentate ligand, connecting the metal atoms into an infinite chain parallel to . In the biphenyl ligand, the two benzene rings make a dihedral angle of 33.19 (7)°.
