Benzotriazolium 4-methyl­benzene­sulfonate

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

Glycinium 3-carb­oxy-4-hy­droxy­benzene­sulfonate

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—H...O hydrogen bonds between the carb­oxy­lic acid groups and sulfonate O atoms. A pair of C—H...O inter­actions is also observed within each dimer. The anion dimers and the cations are linked into a three-dimensional network by N—H...O, O—H...O and C—H...O hydrogen bonds.
