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 stirring overnight. The yellow solid obtained was washed with warm water in a yield of 70.3%. Yellow blocks were grown from its formic solution.
The N-bound H atoms were located in a difference map and their coordinates were refined with Uiso(H) = 1.2 Ueq(N). The C-bound H atoms were positioned geometrically (C—H =0.93 Å) and refined as riding with Uiso(H) = 1.2 Ueq(C).
The title compound crystallizes with two molecules in the
each molecule displays a zwitterion structure with the pyridine N protonated and the amide N deprotonated (Figs. 1 and 2). The relatively short C1—N2 [1.382 (4) Å] and C12—N5 [1.374 (4) Å] distances indicate that the N2 and N5 lone-pair electrons weakly conjugate with pyridinium rings. The benzene ring forms an angle of 85.1 (2) and 89.3 (2)° with the pyridinium ring in the two molecules of the In the addition, the nitro group is inclined to the benzene ring with 73.3 (3)°, and 80.0 (4)°. In the crystal, intermolecular N—H···N and C—H···O hydrogen bonds (Table 1) link the molecules into chains.For zwitterionic forms of N-arylbenzenesulfonamides, see: Yu et al.

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. |

The title compound crystallizes with two molecules in the asymmetric unit; each molecule displays a zwitterion structure with the pyridine N protonated and the amide N deprotonated (Figs. 1 and 2). The relatively short C1—N2 [1.382 (4) Å] and C12—N5 [1.374 (4) Å] distances indicate that the N2 and N5 lone-pair electrons weakly conjugate with pyridinium rings. The benzene ring forms an angle of 85.1 (2) and 89.3 (2)° with the pyridinium ring in the two molecules of the asymmetric unit. In the addition, the nitro group is inclined to the benzene ring with 73.3 (3)°, and 80.0 (4)°. In the crystal, intermolecular N—H···N and C—H···O hydrogen bonds (Table 1) link the molecules into chains.
