In the title mol-ecule, C13H8Cl2O2, the dihedral angle between the benzene rings is 74.53 (9)°. An intra-molecular O-H⋯O hydrogen bond leading to a S(6) ring is observed. In the crystal, the mol-ecules are connected into a three-dimensional network by C-H⋯O and π-π [inter-centroid distance = 3.6254 (10) Å] inter-actions.
