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-HO, C-HO and C-HF 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).
