3-Benzyl-2H-chromen-2-one

Abstract

The title compound, C16H12O2, is a coumarin which was isolated from stones of the Chinese traditional medicine Clausena lansium. The pyrone ring is almost planar, with a mean deviation of 0.0135 (4) Å. The benzene ring (A) of the benzopyrone unit forms dihedral angles of 1.82 (5) and 72.86 (2)°with the pyrone ring and the substituent benzene ring, respectively. The crystal structure is stabilized by weak π-π stacking inter-actions, with a minimum centroid-centroid distance between benzene rings of 3.6761 (7) Å. © Li et al. 2012.
