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-Hâ¯O hydrogen bonds. Dimers oriented in parallel, linked by C-Hâ¯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 70.41â (16)°. They are respectively parallel in a given column or almost perpendicular [oriented at an angle of 87.8â (1)°] in neighbouring (inversely oriented) columns, forming a herringbone pattern.
