In the title compound, C(11)H(11)N(2)O(2)S(+)·NO(3) (-), the dihedral angle between the benzene and pyridinium rings is 87.59 (8)°. An intra-molecular C-H⋯O inter-action occurs in the cation. In the crystal structure, ion pairs occur, being linked by two strong N-H⋯O inter-actions, forming R(2) (2)(8) loops. The packing is further stabilized by weak C-H⋯O inter-actions.
在标题化合物C(11)H(11)N(2)O(2)S(+)·NO(3) (-)中，苯环与吡啶鎓环之间的二面角为87.59 (8)°。阳离子中存在分子内C-H⋯O相互作用。在晶体结构中，通过两个强N-H⋯O相互作用形成离子对，形成R(2) (2)(8)环。通过弱C-H⋯O相互作用进一步稳定了堆积结构。
