✦ Synopsis

In the title compound, C 18 H 16 O 3 , the phenyl ring makes a dihedral angle of 59.67 (4) with the benzene ring of the chromanone unit. The molecular structure is stabilized by a weak intramolecular C-HÁ Á ÁO interaction and the crystal packing is stabilized by weak intermolecular C-HÁ Á ÁO and C-HÁ Á Á interactions.
