In the title salt, C(5)H(6)ClN(2) (+)·C(4)H(5)O(4) (-), the pyridine N atom is protonated. The pyridinium and amino groups associate via a pair of N-H⋯O hydrogen bonds to the carboxyl-ate O atoms of the singly deprotonated succinate anion. The hydrogen succinate anions self-assemble via O-H⋯O hydrogen bonds into chains along the b axis. The crystal structure is further stabilized by additional N-H⋯O hydrogen bonds involving the second amino H atoms, as well as C-H⋯O contacts, forming a three-dimensional network.
在标题盐C(5)H(6)ClN(2) (+)·C(4)H(5)O(4) (-)中，吡啶N原子被质子化。吡啶鎓离子和氨基通过一对N-H⋯O氢键与单去质子化琥珀酸根阴离子的羧酸根O原子缔合。氢琥珀酸根阴离子通过O-H⋯O氢键自组装成沿b轴的链。晶体结构通过涉及第二个氨基H原子的额外N-H⋯O氢键以及C-H⋯O接触进一步稳定，形成三维网络。
