In the title compound, C11H11N2O2S+·NO3−, the dihedral angle between the benzene and pyridinium rings is 87.59 (8)°. An intramolecular C—H⋯O interaction occurs in the cation. In the ion pairs occur, being linked by two strong N—H⋯O interactions, forming R22(8) loops. The packing is further stabilized by weak C—H⋯O interactions.

The title compound was prepared according to the reported literature (Li, Yang et al. 2008). Colourless blocks of (I) were obtained by evaporation of a nitric acid solution of the sulfonamide.
The H atoms bound to C were positioned geometrically (C—H = 0.95Å) and refined as riding with Uiso(H) = 1.2 Ueq(C). The N—H hydrogen atoms were refined with their isotropic displacement parameters, and N—H distances are restrained to 0.86 (2) and 0.91 (2) Å, respectively.

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 as guests for construction of supramolecular complexes. As part of our ongoing studies of host–guest chemistry involving the pyridinium salts (Li et al., 2007; Li, Fan, Fan et al., 2008), the structure of the title compound was determined by X-ray diffraction. For related structures, see: Li et al. (2008a,b).
The title compound, (I), consists of a pyridinium cation and a nitrate anion (Fig. 1). In the cation, the C—N distance [1.378 (2) Å] is short enough to display significant double-bond character (typical C=N = 1.34–1.38 Å), despite the presence of the strong electron-withdrawing sulfonyl group. This could be attributed to the ortho N+ atom in the pyridinium ring. The benzene ring constructs an angle of 87.59 (8)° with the pyridinium ring.
In the crystal structure, two strong N—H···O hydrogen bonds (R22(8)) link the cation and anion, and weak C—H···O interactions (Table 1) help establishing the packing as well as significant ion-dipolar interactions [N2—O2 3.020 at (x - 1, y, z), N2—O3 3.006, N2—O4 3.581, N2—O5 3.377 at (-x + 3/2, y + 3/2, -z + 1/2)]. Besides, one short intramolecular C—H···O contact also occurs in the cation.
