3,5-Dibromo-2-hydroxybenzoic acid
Abstract
The title compound, C7H4Br2O3, has an intramolecular O—H...O=C hydrogen bond and aggregates to form hydrogen-bonded dimers via O—H...O interactions. The formation of zigzag one-dimensional molecular tapes via C—H...Br interactions and π–π stacking interactions (interplanar separation = 3.42 Å) completes the crystal structure.
