title: 2-(4-Fluoro-phen-yl)-2H-chromen-4(3H)-one.
abstract: In the crystal structure of the title compound, C(15)H(11)FO(2), mol-ecules form inversion dimers through pairs of weak C-H⋯O hydrogen bonds. Dimers oriented in parallel, linked by C-H⋯π contacts, are arranged in columns along the b axis. The fluoro-phenyl 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.
