6-Bromo-3-hydroxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid dimethylformamide disolvate

Abstract

In the title compound, C16H9BrO5·2C3H7NO, the chromene ring system is essentially planar. The two dimethylformamide solvent molecules are linked by intermolecular O—H...O hydrogen bonds to the 6-bromo-3-hydroxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid molecules.
