In the title compound, C16H14O4, there is an intramolecular O—HO hydrogen bond. The benzene rings are inclined to one another by 13.89 (9)°. The prop-2-en-1-one group is twisted slightly, the O=C—Car—Car (ar = aromatic) and C=C—C=O torsion angles being −10.4 (3) and −7.4 (3)°, respectively. In the crystal, molecules are linked by O—HO hydrogen bonds, forming chains along [100]. These chains are further linked by O—HO hydrogen bonds, forming corrugated sheets lying parallel to (010). There are C—Hπ interactions present within the sheets.
