In the title complex, [Cu(C12H7Cl2N2O)2], the CuII center is tetracoordinated by two phenolic O and two azomethine N atoms from two bidentate 4-chloro-2-[(2-chloro-3-pyridyl)iminomethyl]phenolate (L) ligands. In the crystal structure, the CuII atom has a distorted square-planar coordination environment. The dihedral angles between the benzene and pyridyl rings are 54.39 (3) and 80.14 (4)°, indicating that the pyridine ring has a considerably weaker steric hindrance. The packing of the molecule is controlled by C—H...π(Ph) interactions and short O...Cl interactions [3.196 (4) Å], linking the molecules into a chain-like structure along the c axis.
