In the title hydrated molecular salt, C7H11N2+·C7H6NO2−·2H2O, the cation is protonated at the pyridine N atom and the dihedral angle between the benzene ring and the CO2−group in the anion is 8.5 (2)°. In the crystal, the cation forms an N—H...O hydrogen bond to the anion and the anion forms two N—H...O hydrogen bonds to adjacent water molecules. Both water molecules form two O—H...O hydrogen bonds to carboxylate O atoms. In combination, these hydrogen bonds generate a three-dimensional network and two weak C—H...π interactions are also observed.
