Abstract: The title compound, C₇H₄Br₂O₂, exhibits a layer packing structure via weak - stacking interactions [centroid-centroid distances between adjacent aromatic rings are 4.040 (8) and 3.776 (7) Å]. Molecules in each layer are linked by intermolecular O-HO hydrogen bonding and BrBr interactions [3.772 (4) Å]. There are two molecules in the asymmetric unit.
