2-(4-Fluorophenyl)-3-hydroxy-4H-chromen-4-one

Abstract

In the crystal structure of the title compound, C15H9FO3, inversely oriented molecules form inversion dimers through pairs of O—H...O hydrogen bonds. The benzene ring is twisted at an angle of 12.0 (1)° relative to the 4H-chromene skeleton of the molecule. Adjacent 4H-chromene units are parallel in a given column or oriented at an angle of 50.0 (1)° in neighboring, inversely oriented, columns, forming a herringbone pattern.
