In the title compound, C20H13ClO3, the dihedral angles between the benzoate and the chloro­benzene and benzoyl rings are 68.82 (5) and 53.76 (6)°, respectively, while the dihedral angle between the benzoyl and benzoate rings is 81.17 (5)°. The eight atoms of the benzoyl residue are essentially planar with the exception of the O atom which lies 0.1860 (5) Å out of their mean plane (r.m.s. deviation = 0.97 Å). The nine atoms of benzoate residue are also essentially planar (r.m.s. deviation = 0.20 Å) with the ester O atom showing the greatest deviation [0.407 (12) Å] from their mean plane. In the crystal, mol­ecules are connected into centrosymmetric dimers by pairs of C—H...O hydrogen bonds.

In the title mol­ecule, C13H8Cl2O2, the dihedral angle between the benzene rings is 74.53 (9)°. An intra­molecular O—H...O hydrogen bond leading to a S(6) ring is observed. In the crystal, the mol­ecules are connected into a three-dimensional network by C—H...O and π–π [inter-centroid distance = 3.6254 (10) Å] inter­actions.

In the mol­ecule of the title compound, C15H14O2, the dihedral angle between the benzene and phenyl rings is 61.27 (8)°. In the crystal, O—H...O and weak C—H...O hydrogen bonds link the mol­ecules into chains extending along the c-axis direction.
