3-Benzoyl-7-methoxy-2H-chromen-2-one

Abstract

In the title compound, C17H12O4, the dihedral angle between the coumarin ring system (r.m.s. deviation = 0.018 Å) and the phenyl ring is 55.96 (8)°. In the crystal, weak C—H...O interactions connect the molecules into a three-dimensional network and aromatic π–π stacking interactions are also observed [shortest centroid–centroid separation = 3.6692 (9) Å].
