3,5-Dibromo-2-hydroxybenzoic acid

The title compound, C7H4Br2O3, has an intramolecular O-H center dot center dot center dot O = C hydrogen bond and aggregates to form hydrogen-bonded dimers via O-H center dot center dot center dot O interactions. The formation of zigzag one-dimensional molecular tapes via C-H center dot center dot center dot Br interactions and pi-pi stacking interactions (interplanar separation = 3.42 angstrom) completes the crystal structure.
