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.
