Abstract

In the title compound, C17H10Br2O5, the chromene ring is almost planar with minimal puckering [total puckering amplitude = 0.067 (4) angstrom]. The dihedral angle between chromeme ring system and phenyl ring is 3.7 (2)degrees. The crystal structure is stabilized by intermolecular C-H center dot center dot center dot O interactions and an intramolecular O-H center dot center dot center dot O hydrogen bond also occurs.
