In the title compound, C16H13ClO3, the dihedral angle between the benzene rings is 80.74 (8)°. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules to form C(11) chains propagating in [010].

In the title compound, C15H11BrO4, the dihedral angle between the aromatic rings is 66.77 (8)°. In the crystal, O—H⋯O, C—H⋯Br and C—H⋯O hydrogen bonds link the mol­ecules, forming layers lying parallel to (101). The crystal packing is further consolidated by C—H⋯π inter­actions and π–π stacking inter­actions [centroid–centroid distance = 3.5476 (7) Å].
