The title mol-ecule, C(16)H(12)Cl(4)N(2)O(2), lies about an inversion center. The symmetry-unique part of the mol-ecule contains an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules are arranged in corrugated layers parallel to (-101). Weak π-π stacking inter-actions, with a centroid-centroid diatance of 3.7923 (13) Å, are present.
