Abstract [en]

The title compound, C4H3BrO4, was obtained from a solution of meso-2,3-dibromosuccinic acid and vanadium(IV) oxide. The crystals are isostructural with chloromaleic acid and the molecule has two geometrically different carboxyl groups, one of which has delocalized C-O bonds and is essentially coplanar with the olefinic bond plane [give dihedral angle 15.08 (16)degrees], whereas the other has a localized C=O bond and forms a dihedral angle of 99.6 (3)degrees with the C C bond plane. Two symmetry-independent O-H center dot center dot center dot O hydrogen bonds link the molecules into layers parallel to the bc plane.
