Abstract: In the title molecule, C22H20O5, the C=C bond of the central enone group adopts an E conformation. The dihedral angle formed by the benzene ring and the naphthalene ring system is 12.6 (4)°. The hydroxy group attached to the naphthalene ring is involved in an intramolecular O-HO hydrogen bond. In the crystal, weak C-HO hydrogen bonds link the molecules into chains along . In addition, - stacking interactions are present, with centroid-centroid distances of 3.6648 (15) and 3.8661 (15) Å between the benzene and two naphthalene rings.
