4-(2-Nitro-benzene-sulfonamido)pyri-dinium trifluoro-acetate
Abstract:
In the title compound, C(11)H(10)N(3)O(4)S(+)·C(2)F(3)O(2) (-), 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).
