3-Hydroxy-2-(4-hydroxyphenyl)-4H-chromen-4-one

Abstract

In the title compound, C15H10O4, the benzene ring is twisted at an angle of 20.7 (1)° relative to the 4H-chromene skeleton. In the crystal, adjacent molecules are linked via a network of O—H...O and C—H...O hydrogen bonds. The mean planes of adjacent 4H-chromene moieties are parallel or oriented at an angle of 20.9 (1)° in the crystal structure.
