The mol-ecular shape of the title compound, C16H12O7, is bent around the central CH2-O bond. The two benzene rings are almost perpendicular to one another, making a dihedral angle of 87.78 (7)°. In the crystal, each mol-ecule is linked to three others by three pairs of O-H⋯O hydrogen bonds, forming undulating sheets parallel to the bc plane and enclosing R 2 (2)(8) ring motifs. The sheets are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional network.
