In the title Schiff base complex, [Cu(C19H16Cl4N2O2)], the geometry around the CuII atom is distorted square-planar defined by the N2O2 donor atoms of the coordinated ligand. The dihedral angle between the substituted benzene rings is 29.95 (16)°. In the crystal, mol­ecules are linked along the b axis, forming individual dimers through C—H⋯O inter­actions. The crystal structure is further stabilized by inter­molecular π–π inter­actions [centroid–centroid distance = 3.6131 (17) Å].
