The title compound, C17H14Cl4N2O2, is generated by crystallographic twofold symmetry. The two benzene rings are inclined to one another by 80.17 (10)°. There are two intramolecular O—H⋯N hydrogen bonds, which make S(6) ring motifs. In the crystal, molecules are linked by C—H⋯O and weak C—H⋯Cl interactions, forming a three-dimensional network.
