Abstract

In the title compound, C(16)H(12)Cl(2)O(3), the benzene rings form a dihedral angle of 2.0 (3)°. Within the central O=C-CH(2)C(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, inter-molecular O-H⋯O hydrogen bonds formed between the hydr-oxy groups lead to a supra-molecular chain along the c axis. In addition, the crystal packing features some very weak C-H⋯π inter-actions.
