Crystal structure of 3-[4-(benz-yloxy)phen-yl]-2,3-di-hydro-1H-benzo[f]chromen-1-one.

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, mol-ecules 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?? inter-actions, forming sheets lying parallel to (010).
