In the crystal structure of the title compound, C15H11FO2, molecules form inversion dimers through pairs of weak C—H
O hydrogen bonds. Dimers oriented in parallel, linked by C—Hπ contacts, are arranged in columns along the b axis. The fluorophenyl ring and the benzene ring of the 2H-chromen-4(3H)-one unit are inclined to one another by 70.41 (16)°. They are respectively parallel in a given column or almost perpendicular [oriented at an angle of 87.8 (1)°] in neighbouring (inversely oriented) columns, forming a herringbone pattern.
