In the title salt, C(5)H(7)N(2) (+)·C(4)H(5)O(4) (-), the asymmetric unit comprises an amino-pyridinium cation and a hydrogen succinate anion as protonation of the aromatic N atom of the 4-amino-pyridine mol-ecule has occurred. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds that lead to a two-dimensional array. Short C-H⋯O contacts are also present.
在标题盐C(5)H(7)N(2) (+)·C(4)H(5)O(4) (-)中，不对称单元包含一个氨基吡啶鎓阳离子和一个氢琥珀酸根阴离子，因为4-氨基吡啶分子的芳香族N原子发生了质子化。晶体堆积通过分子间的O-H⋯O和N-H⋯O氢键得以稳定，形成二维阵列。还存在短的C-H⋯O接触。
