In the title compound, C16H14O4, the benzene rings are inclined to one another by 4.91 (7)°. The conformation about the C=O and C=C bonds is trans and cis, respectively. In the crystal, molecules are linked by O—H
O hydrogen bonds, forming inversion dimers with an R22(14) ring motif. The dimers are linked via O—HO and C—HO hydrogen bonds, forming undulating two-dimensional networks lying parallel to (10-1). These networks are linked by further C—HO hydrogen bonds, forming a three-dimensional structure.

In the title compound, C26H20O3, the pyran ring has a distorted half-chair conformation and its mean plane is inclined to the naphthalene ring system, to which it is fused, by 10.79 (9)°. The dihedral angles between the napthalene unit and the benzene and phenyl rings are 54.39 (9) and 52.65 (12)°, respectively, while the benzene and phenyl rings are inclined to one another by 74.80 (14)°. There is a short C—HO contact in the chromen-1-one unit. In the crystal, molecules are linked by two pairs of C—HO hydrogen bonds, forming inversion dimers described by graph set motifs R22(8) and R22(10), giving rise to chains running parallel to (101). The chains are linked via C—Hπ interactions, forming sheets lying parallel to (010).
