In the mononuclear title complex, [Cu(C 18 H 14 Cl 2 N 3 O 2 ) 2 ], the Cu II atom is coordinated by two N atoms and two O atoms from the Schiff base ligands in a square-planar geometry, with a dihedral angle between the two chelate NCuO planes of 31.57 (3) . The Cu atom is located on a twofold axis
