    In the title compound, C11H10N3O4S+·C2F3O2 −, the benzene ring makes an angle of 87.3 (2)° with the pyridinium ring. The nitro group is essentially coplanar with the benzene ring. The F atoms of the CF3 group are disordered over two positions with almost equal occupancy [0.531 (12)/0.469 (12)]. The crystal structure is stabilized by N—H⋯O and C—H⋯O hydrogen bonds
