Uronium 3-carb-oxy-4-hy-droxy-benzene-sulfonate.
In the title compound, CH5N2O(+)·C7H5O6S(-), the dihedral angle between the benzene ring and the mean plane of the uronium cation is 76.02 (8)°. The carboxyl group in the anion is twisted by 1.47 (9)° from the benzene ring. In the crystal, the cation is linked to the anion by weak O-H⋯O and N-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distance = 3.8859 (8) Å], forming a three-dimensional network.
