چکیده
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.

In the crystal structure of the title compound, [Mg(H(2)O)(6)](C(7)H(5)O(6)S)(2)·2H(2)O, the octa-hedral complex cation lies on an inversion centre and is hydrogen bonded through the coordinated water molecules to the substituted benzene-sulfonate monoanions and the water mol-ecules of solvation. These inter-actions together with a carb-oxy-lic acid O-H⋯O(sulfonate) association give a three-dim...
