Abstract: In the crystal structure of the title hydrate, C8H4Br2O4·H2O, O-HO hydrogen bonds link the molecules into a two-dimensional network parallel to (10-2). The acid groups of the main molecule and the water molecule are all involved in the supramolecular structure. The dihedral angles between the benzene ring and the acid groups are 37.8 (4) and 36.4 (5)°, while the dihedral angle between the acid groups is 10.9 (4)°.
