✦ Synopsis

In the title compound, C~20~H~18~O~3~, the phenyl ring makes a dihedral angle of 50.41 (10)° with the benzene ring of the chromanone unit. The molecular structure is stabilized by weak intramolecular C—H...O interactions and the crystal packing is stabilized by weak intermolecular C—H...O interactions.
