Abstract
The title compound, C7H4Br2O2, crystallizes as centrosymmetric dimers in which two molecules are linked by two hydrogen bonds between the hy droxyl and carbonyl groups, with an O ... O distance of 2.839(5) Angst rom. Other intermolecular interactions are weak. There are no unusual intramolecular bond distances or angles. The atoms of the aldehyde gro up and the Br atoms, however, are found to deviate significantly from the plane of the benzene ring.
