title: 6-Bromo-3-hydr-oxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid dimethyl-formamide disolvate.
abstract: In the title compound, C(16)H(9)BrO(5)·2C(3)H(7)NO, the chromene ring system is essentially planar. The two dimethyl-formamide solvent mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds to the 6-bromo-3-hydr-oxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid molecules.
