4-(2-Nitrobenzenesulfonamido)pyridinium nitrate

L. Zhao and Q.-F. Yu

Abstract: There are two molecules in the asymmetric unit of the title compound, C₁₁H₁₀N₃O₄S⁺·NO₃^-. All bond distances have normal values. The C-N bond distances in the sulfonamide group [1.389 (3) and 1.382 (3) Å] may indicate slight conjugation of the sulfonamide N-atom -electrons with those of the pyridinium ring. The crystal structure is stabilized by N-HO hydrogen bonds.
