In the molecule of the title compound, C14H14ClNO2S, the N—H bond is in a syn position with respect to the meta-Cl atom in the aniline ring. The molecule is twisted about the N—S bond with a C—SO2—NH—C torsion angle of 44.55 (17)°. The two aromatic rings are inclined relative to each other by 66.2 (1)°. In the crystal, N—H⋯O hydrogen bonds link the molecules into infinite chains parallel to the b axis.

The solution of 1,3-xylene (1,3-dimethylbenzene) (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 2,4-dimethylbenzenesulfonylchloride was treated with 3-chloroaniline 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 cc). The resultant solid N-(3-chlorophenyl)-2,4-dimethylbenzenesulfonamide 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 (Savitha & Gowda, 2006).
The prism like colourless single crystals used in X-ray diffraction studies were grown in ethanolic solution by a slow evaporation at room temperature.
The H atom of the NH group was located in a difference map and later restrained to the distance N—H = 0.86 (2) Å. The other H atoms were positioned with idealized geometry using a riding model with the aromatic C—H = 0.93Å and methyl C—H = 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. |

The amide and sulfonamide moieties are the constituents of many biologically important compounds. The hydrogen bonding preferences of sulfonamides have been investigated (Adsmond & Grant, 2001). As part of our work on the substituent effects on the structures and other aspects of N-(aryl)-amides (Arjunan et al., 2004; Gowda et al., 1999), N-(aryl)-methanesulfonamides (Gowda et al., 2007) and N-(aryl)-arylsulfonamides (Gowda et al., 2010), in the present work, the crystal structure of N-(3-chlorophenyl)-2,4-dimethylbenzene- sulfonamide (I) has been determined (Fig. 1). The conformation of the N—C bond in the C—SO2—NH—C segment has gauche torsions with respect to the S═O bonds. The molecule is bent at the S atom with the C1—SO2—NH—C7 torsion angle of 44.6 (2)°, compared to the values of -54.9 (2)° in N-(2-chlorophenyl)-2,4-dimethylbenzenesulfonamide (II) (Gowda et al., 2010). Further, the conformation of the N—H bond in (I) is syn to the meta-chloro group in the anilino ring.
The two benzene rings in (I) are tilted relative to each other by 75.7 (1)°, compared to the value of 66.2 (1)° (II). The other bond parameters in (I) are similar to those observed in (II) and other aryl sulfonamides (Perlovich et al., 2006; Gelbrich et al., 2007).
The crystal packing of molecules in (I) via N—H···O(S) hydrogen bonds (Table 1) is shown in Fig.2.
