Comment

As part of a study of the substituent effects on the crystal structures of N-(aryl)-arylsulfonamides (Gowda et al., 2009a, b; 2010), the structure of 4-methyl-N-(2,3-dimethylphenyl)-benzenesulfonamide (I) has been determined (Fig. 1). The conformation of the N—H bond in (I) is anti to the ortho- and meta-methyl groups. The molecule is bent at the S atom with the C—SO2—NH—C torsion angle of 80.2 (2)°, compared to the values of -61.0 (2)° in 4-methyl-N-(2,5-dimethylphenyl)-benzenesulfonamide (II) (Gowda et al., 2010), -51.6 (3)° in 4-Methyl-N-(phenyl)- benzenesulfonamide (III) (Gowda et al., 2009b) and 71.0 (2)° in N-(2,3-dimethylphenyl)benzenesulfonamide (IV) (Gowda et al., 2009a). The two benzene rings in (I) are tilted relative to each other by 38.3 (1)°, compared to the values of 49.4 (1)° in (II), 68.4 (1)° in (III) and 64.8 (1)° in (IV). The other bond parameters in (I) are similar to those observed in (II), (III), (IV) and other aryl sulfonamides (Perlovich et al., 2006; Gelbrich et al., 2007). The packing of molecules via N—H···O hydrogen bonds (Table 1) into infinite chains is shown in Fig. 2.

Experimental

The solution of toluene (10 ml) in chloroform (40 ml) was treated dropwise with chlorosulfonic acid (25 ml) at 0 ° C. After the initial evolution of hydrogen chloride subsided, the reaction mixture was brought to room temperature and poured into crushed ice in a beaker. The chloroform layer was separated, washed with cold water and allowed to evaporate slowly. The residual 4-methylbenzenesulfonylchloride was treated with 2,3-dimethylaniline in the stoichiometric ratio and boiled for ten minutes. The reaction mixture was then cooled to room temperature and added to ice cold water (100 ml). The resultant 4-methyl-N-(2,3-dimethylphenyl)benzenesulfonamide was filtered under suction and washed thoroughly with cold water. It was then recrystallized to constant melting point from dilute ethanol. The purity of the compound was checked and characterized by recording its infrared and NMR spectra (Shetty & Gowda, 2005).

Rod like colourless single crystals used in X-ray diffraction studies were grown in ethanolic solution by a slow evaporation at room temperature.

Refinement

The H atom of the NH group was located in a difference map and later restrained to the distance N—H = 0.86 (1) Å. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.96 Å. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

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.
