In the title hydrated mol-ecular 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 mol-ecules. Both water mol-ecules form two O-H⋯O hydrogen bonds to carboxyl-ate O atoms. In combination, these hydrogen bonds generate a three-dimensional network and two weak C-H⋯π inter-actions are also observed.
在标题水合分子盐C₇H₁₁N₂⁺·C₇H₆NO₂⁻·2H₂O中，阳离子在吡啶N原子处质子化，阴离子中苯环与CO₂⁻基团之间的二面角为8.5(2)°。在晶体中，阳离子与阴离子形成N-H⋯O氢键，阴离子与相邻水分子形成两个N-H⋯O氢键。两个水分子均与羧酸根O原子形成两个O-H⋯O氢键。这些氢键共同形成三维网络，并且还观察到两个弱的C-H⋯π相互作用。
