title: 2-(Benzene-sulfonamido)pyridinium nitrate.
abstract: 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.
