Abstract
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—H⋯O contact in the chromen-1-one unit. In the crystal, molecules are linked by two pairs of C—H⋯O hydrogen bonds, forming inversion dimers described by graph set motifs R 2 2(8) and R 2 2(10), giving rise to chains running parallel to (101). The chains are linked via C—H⋯π interactions, forming sheets lying parallel to (010).
