Abstract
In the title compound, C16H14Cl2O3, the dihedral angle between the mean planes of the two benzene rings is 55.30 (5)°. The methyl ester group lies within the ring plane due to an intramolecular O—H⋯O hydrogen bond [maximum deviation from the C8O2 mean plane is 0.0383 (13) Å]. In the crystal, molecules are held together by rather weak C—H⋯O hydrogen bonds.
