In the title molecular salt, C6H6N3+·C7H7O3S−, the components are linked by N—HO hydrogen bonds into zigzag chains along [100]. These chains are further connected by weak C—HO, C—Hπ and π–π (centroid-to-centroid distances = 3.510, 3.701 and 3.754 Å) interactions into a three-dimensional network.

In the anion of the title salt, C2H6NO2+·C7H5O6S−, the dihedral angle between the carboxylic acid group and the benzene ring is 5.02 (12)°. In the crystal, the anions are linked into inversion dimers through pairs of O—HO hydrogen bonds between the carboxylic acid groups and sulfonate O atoms. A pair of C—HO interactions is also observed within each dimer. The anion dimers and the cations are linked into a three-dimensional network by N—HO, O—HO and C—HO hydrogen bonds.

In the title hydrated molecular salt, C8H12N+·C6H4NO3−·H2O, the conformation of the side chain in the cation is anti [C—C—C—N = 179.62 (12)°] and the dihedral angle between the aromatic ring and the nitro group in the anion is 3.34 (11)°. In the crystal, the components are linked by O—HO and N—HO hydrogen bonds, generating (10-1) sheets, which feature R44(21) loops. The sheets interact by weak aromatic π–π stacking interactions [centroid–centroid distance = 3.896 (3) Å], forming a three-dimensional network.
