title: 4-(4-Nitro-benzene-sulfonamido)pyridinium nitrate.
abstract: A short C-N distance [1.394 (2) Å] in the title compound, C(11)H(10)N(3)O(4)S(+)·NO(3) (-), is indicative of some conjugation of the sulfonamide π electrons with those of the pyridinium ring. The crystal structure is stabilized by N-H⋯O hydrogen bonds.
