In the title compound, C(5)H(7)N(2) (+)·C(7)H(5)O(3) (-), the carboxyl-ate mean plane of the 4-hydroxy-benzoate anion is twisted by 8.78 (5)° from the attached ring. The cations and anions are linked via O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network. In addition, π-π inter-actions involving the benzene and pyridinium rings, with centroid-centroid distances of 3.5500 (6) and 3.6594 (6) Å, are observed.
在标题化合物C(5)H(7)N(2) (+)·C(7)H(5)O(3) (-)中，4-羟基苯甲酸根阴离子的羧酸根平均平面与相连环扭转了8.78 (5)°。阳离子和阴离子通过O-H⋯O、N-H⋯O和C-H⋯O氢键相连，形成三维网络。此外，观察到涉及苯环和吡啶鎓环的π-π相互作用，其质心-质心距离分别为3.5500 (6) 和3.6594 (6) Å。
