There are two molecules in the asymmetric unit of the title compound, C11H10N3O4S+·NO3-. All bond distances have normal values. The C-N bond distances in the sulfonamide group [1.389 (3) and 1.382 (3) Å] may indicate slight conjugation of the sulfonamide N-atom
-electrons with those of the pyridinium ring. The crystal structure is stabilized by N-H
O hydrogen bonds.
A solution of 2–nitrobenzenesulfonyl chloride (2.2 g, 10 mmol) in CH2Cl2 (10 ml) was added dropwise to a suspension of 4–aminopyridine (0.9 g, 10 mmol) in CH2Cl2 (10 ml) at room temperature with stirring. The reaction mixture was stirred overnight. The yellow solid obtained was washed with warm water to obtain the title compound in a yield of 52.9%. A colourless single crystals, suitable for X–ray analysis were obtained by slow evaporation of an nitric acid (10%) solution at room temperature over a period of a week.
The N–bound H atoms were located in a difference map and refined isotropically. The C–bound H atoms were positioned geometrically (C—H = 0.95 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 (Damiano et al., 2007). 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 [N2–C1 = 1.389 (3)Å and N5–C12 = 1.382 (3)Å] has a value between those of a typical C═N double and C—N single bond (1.47–1.50Å and 1.34–1.38Å, respectively; Allen et al., 1987). This might be indicative of a slight conjugation of the N sulfonamide π–electrons with those of the pyridinium ring. In the two symmetry–independent molecules (Fig. 1), the dihedral angles between the benzene ring and the pyridinium ring are 85.1 (1)° and 86.2 (1)° respectively. The dihedral angles between the nitro–group and the benzene ring are 41.2 (1)° and 40.5 (2)° respectively.
