In the title salt, C(6)H(9)N(2) (+)·C(7)H(4)ClO(2) (-), the 2-amino-4-methyl-pyridinium cation is almost planar, with a maximum deviation of 0.010 (1) Å. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are further connected via N-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.
在标题盐C(6)H(9)N(2) (+)·C(7)H(4)ClO(2) (-)中，2-氨基-4-甲基吡啶阳离子几乎呈平面状，最大偏差为0.010 (1) Å。在晶体中，阳离子的质子化N原子和2-氨基通过一对N-H⋯O氢键与阴离子的羧酸根O原子形成氢键，形成R(2) (2)(8)环 motif。离子对通过N-H⋯O和C-H⋯O氢键进一步连接，形成平行于bc平面的二维网络。
