| Popis: | In the title compound, C20H16O3, the hydropyran ring adopts a distorted half-chair conformation with the methine C atom and the ring O atom displaced by −0.554 (2) and 0.158 (1) Å, respectively, from the plane of the other four atoms (r.m.s. deviation = 0.020 Å). Its mean plane (all atoms) is inclined to the naphthalene ring system at a dihedral angle of 11.67 (1)°. The dihedral angle between the napthalene ring system and the phenyl ring is 71.84 (1)°. In the crystal, no diectional interactions beyond van der Waals contacts could be identified. |
