Glycinium 3-carb­oxy-4-hy­droxy­benzene­sulfonate


In the anion of the title salt, C2H6NO2 (+)·C7H5O6S(-), the dihedral angle between the carb-oxy-lic 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 carb-oxy-lic acid groups and sulfonate O atoms. A pair of C-H⋯O inter-actions 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.
