Abstract: In the solid-state structure of the title compound, C₁₆H₁₁BrO₄, the configuration about the double bond is E, and the mean planes through the two aromatic rings are inclined to one another by 63.71 (12)°. In the crystal structure, symmetry-related molecules are linked by O-HO hydrogen bonds, forming centrosymmetric carboxylic acid dimers. The crystal structure is further stabilized by C-HBr and C-HO intermolecular hydrogen bonds, leading to the formation of a layer-like structure, which extends in the ab plane.
