چکیده
In the title mol-ecule, 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 hy-droxy group attached to the naphthalene ring is involved in an intra-molecular O-H⋯O hydrogen bond. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into chains along [010]. In addition, π-π stacking inter-actions are present, with centroid-centroid distances of 3.6648 (15) and 3.8661 (15) Å between the benzene and two naphthalene rings.
