In the title salt, C(6)H(9)N(2) (+)·NO(3) (-), the 2-amino-5-methyl-pyridinium cation and the nitrate anion are cyclically linked through pyridinium and amine N-H⋯O hydrogen bonds [graph set R(4) (3)(12)]. These units are extended into a zigzag chain structure lying parallel to the a axis, through a second cyclic R(2) (2)(8) association involving amine N-H⋯O and aromatic C-H⋯O hydrogen bonds to nitrate O-atom acceptors.
在标题盐C(6)H(9)N(2) (+)·NO(3) (-)中，2-氨基-5-甲基吡啶阳离子和硝酸根阴离子通过吡啶鎓和胺N-H⋯O氢键[图集合R(4) (3)(12)]呈环状相连。这些单元通过涉及胺N-H⋯O和芳香族C-H⋯O与硝酸根O原子受体的第二个环状R(2) (2)(8)缔合，延伸成平行于a轴的锯齿链结构。
