In the title compound, C16H12Cl2O3, the benzene rings form a dihedral angle of 2.0 (3)°. Within the central O=C—CH2C(H)OH—C=O unit, the carbonyl groups are coplanar and lie to opposite sides [O—C...C—O = −170.1 (6)°]. In the crystal, intermolecular O—H...O hydrogen bonds formed between the hydroxy groups lead to a supramolecular chain along the c axis. In addition, the crystal packing features some very weak C—H...π interactions.
