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 is stabilized by N—H⋯O and C—H⋯O hydrogen bonds.

4-Nitro-(N-pyridyl)benzenesulfonamide was prepared by the method of Yu & Li (2007). Crystals were obtained by evaporation of a trifluoroacetic acid solution of the amide.
The N-bound H atoms were located in a difference map and their coordinates were refined. The C-bound H atoms were positioned geometrically (C—H = 0.93 Å) and refined as riding atoms. The constraint Uiso(H) = 1.2 Ueq(C and N) was applied. The N1—H1A distance was restrained at 0.90 (1) Å and C—F distances to 1.36 (1) Å. The instruction ISOR (tolerance 0.01) was applied to restrain the displacement ellipsoids of all F atoms to an isotropic bahaviour. The CF3 group was disordered with the occupancy of 0.531 (12):0.469 (12).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Organic pyridinium salts have been widely used in the construction of supramolecular architectures. As part of our ongoing studies of supramolecular chemistry involving the pyridinium rings (Li et al., 2007), the structure of the title compound was determined by X-ray diffraction.
In the cations of the title compound the short C—N distance is indicative of the slight conjugation of the sulphonamide N with the pyridinium ring. The benzene ring forms an angle of 87.3 (2)° with the pyridinium ring. The nitro group is essentially coplanar with the benzene ring
The crystal packing is stabilized by N—H···O and C—H···O hydrogen bonds.
