4,6-Dibromo­isophthalic acid monohydrate

In the crystal structure of the title hydrate, C₈H₄Br₂O₄·H₂O, O—H...O 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)°.
