4-(4-Nitrobenzenesulfonamido)pyridinium bromide

L. Zhao, Q.-F. Yu and Q. Wu

Abstract top

In the title compound, C11H10N3O4S+·Br-, the benzene ring makes an angle of 88.4 (2)° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 16.5 (2)°. The ions in the crystal structure are linked by a combination of intermolecular N-H...Br and non-conventional C-H...Br and C-H...O hydrogen bonds, forming a three-dimensional network.

Comment top

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), an X-ray structure analysis of the title compound has been performed. In the cations of the title compound the short C—N distance [N2—C3 = 1.387 (3) Å] has a value between those of a typical C=N double and C—N single bond (1.34–1.38 Å and 1.47–1.50 Å, respectively; Allen et al., 1987). This might be indicative of a slight conjugation of the sulphonamide π electrons N with those of the pyridinium ring. The benzene ring makes an angle of 88.4 (2) ° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 163.5 (2) °. The S atom has a tetrahedral geometry and the Br anion link the cationic molecule into chains along the c axis. The ions in the crystal structure are linked by a combination of intermolecular N—H···Br and non-conventional C—H···Br and C—H···O hydrogen bonds (Table 1) to form a three-dimensional network (Desiraju & Steiner, 2001).

Experimental top

A solution of 4-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 60.6%. A colorless single-crystal suitable for X-ray analysis was obtained by slow evaporation of an hydrobromic acid (5%) solution at room temperature over a period of a week. Analysis calculated for C11H10N3O4SBr: C 36.68, H 2.80, N 11.67%; found: C 36.70, H 2.52, N 11.98%.

Refinement top

The N-bound H atoms were located in a difference map and their coordinates were refined with Uiso(H) = 1.2Ueq(N). The C-bound H atoms were positioned geometrically (C—H =0.95 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).

Special details top

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.
