4-Nitro-N-(4-pyridinio)benzenesulfonamidate monohydrate

Abstract top

The title compound, C11H9N3O4S·H2O, contains both an acid and a base centre, and displays a zwitterionic structure in the solid state. The benzene ring makes an angle of 109.1 (2)° with the pyridinium ring. The crystal structure is stabilized by O-H...N, O-H...O and N-H...O hydrogen bonds.

Comment top

Organic pyridinium salts have been widely used in the construction of supramolecular architectures (Teresa 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 (I) was determined by X-ray diffraction.

In the cations of (I) (Fig. 1), the short C—N distance [N2—C1 = 1.370 (3) Å] has a value between those of a typical C═N double and C—N single bond [1.47–1.50 Å and 1.34–1.38 Å, respectively; Allen et al., 1987]. This might be indicative of a slight π electron conjugation of the sulphonamide N with the pyridinium ring. The benzene ring exhibits an angle of 109.1 (2) ° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 2.2 (1) °.

The crystal structure is stabilized by O—H···N, O—H···O and N—H···O hydrogen bonds (Table 1).

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 55.3%. A colourless single-crystal suitable for X-ray analysis was obtained by slow evaporation of an acetic acid solution at room temperature over a period of a week.

Refinement top

The H atoms of the water molecule were found on a difference Fourier map and refined freely. 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.
