Comment top

In the present work, as part of a study of the effect of substituents on the crystal structures of N-(aryl)-arylsulfonamides (Gowda et al., 2008, 2009, 2010), the structure of N-(2,6-dimethylphenyl)-4-methylbenzenesulfonamide (I) has been determined. The molecule is bent at the S atom (Fig. 1) with the C1—SO2—NH—C7 torsion angle of 88.0 (2)°, compared to the values of -51.6 (3)° in N-(phenyl)4-methylbenzenesulfonamide (II) (Gowda et al., 2009), -78.7 (2)° in N-(2,6-dimethylphenyl)- benzenesulfonamide (III) (Gowda et al., 2008) and -61.0 (2)° in N-(2,5-dimethylphenyl)-4-methylbenzenesulfonamide (IV), -61.8 (2)° in N-(3,4-dimethylphenyl)-4-methylbenzenesulfonamide (V) and 56.8 (2)° in N-(3,5-dimethylphenyl)-4-methylbenzenesulfonamide (VI)(Gowda et al., 2010).

The two benzene rings in (I) are tilted relative to each other by 49.8 (1)°, compared to the values of 68.4 (1)° in (II), 44.9 (1)° in (III), 49.4 (1)° in (IV), 47.8 (1)° in (V) and 53.9 (1)° in (VI). The other bond parameters are similar to those observed in (II), (III), (IV), (V), (VI) and other aryl sulfonamides (Perlovich et al., 2006; Gelbrich et al., 2007).

In the crystal structure, the intermolecular N–H···O hydrogen bonds (Table 1) link the molecules into infinite zig-zag chains running parallel to the a-axis. Part of the crystal structure is shown in Fig. 2.

Experimental top

4-Methylbenzenesulfonylchloride was obtained by treating the solution of toluene (10 ml) in chloroform (40 ml) with chlorosulfonic acid (25 ml) by the procedure reported earlier (Gowda et al., 2010). 4-Methylbenzenesulfonylchloride was then treated with 2,6-dimethylaniline in the stoichiometric ratio to obtain N-(2,6-dimethylphenyl)- 4-methylbenzenesulfonamide. The latter was recrystallized to constant melting point (110 °C) from dilute ethanol. The purity of the compound was checked and characterized by recording its infrared and NMR spectra (Shetty & Gowda, 2005).

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

Refinement top

The H atom of the NH group was located in a difference map and later restrained to 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).

Special details top

Experimental. CrysAlis RED (Oxford Diffraction, 2009) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
