Abstract: In the crystal structure of the title compound, C8H5NO6, both carboxyl groups are involved in intermolecular centrosymmetric cyclic O-HO hydrogen-bonding associations, which give a zigzag chain structure extending along (21). Weak - stacking interactions are also present [minimum ring centroid separation = 3.893 (4) Å].
