4-(2-Nitrobenzenesulfonamido)pyridinium trifluoroacetate

Abstract

In the title compound, C11H10N3O4S+·C2F3O2 −, the dihedral angle between the benzene ring and the pyridinium ring is 88.7 (4)°. In the crystal structure, a network of N—H⋯O, C—H⋯O and C—H⋯F hydrogen bonds links the constituent ions. One O atom of the nitro group is disordered over two positions, with site-occupancy factors of 0.57 (2) and 0.43 (2).
