In the title molecular salt, C12H12N22+·2C7H5O5S−, the complete dication is generated by crystallographic inversion symmetry. In the anion, the sulfonic acid group is deprotonated and the dihedral angle between the planes of the carboxylic acid group and the benzene ring is 12.41 (11)°. In the crystal, the anions are linked into inversion dimers by pairs of O—H...O hydrogen bonds, which generateR22(16) loops. The dications link the anion dimers into [10-2] chainsviaN—H...O hydrogen bonds.
