The solution of chlorobenzene (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-chlorobenzenesulfonylchloride was treated with m-toluidine 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-chloro-N-(3-methylphenyl)-benzenesulfonamide was filtered under suction and washed thoroughly with cold water. It was then recrystallized to constant melting point from dilute ethanol. The compound was characterized by recording its infrared and NMR spectra.
Needle like colorless single crystals used in X-ray diffraction studies were grown in ethanolic solution by 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 the 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 sulfonamide moieties are the constituents of many biologically important compounds. The hydrogen bonding preferences of sulfonamides has been investigated (Adsmond & Grant, 2001). As a part of studying the substituent effects on the structures of this class of compounds (Gowda et al., 2004, 2007, 2010; Nirmala et al., 2009, Shakuntala et al., 2011), in the present work, the crystal structure of 4-chloro-N-(3-methylphenyl)-benzenesulfonamide (I) has been determined (Fig.1). In the title compound, the N—C bond in the C—SO2—NH—C segment has gauche torsions with respect to the S═O bonds. Furthermore, the N—H bond is anti to the meta-methyl group in the anilino ring, similar to that observed in 4-methyl-N-(3-methylphenyl)-benzenesulfonamide (II) (Nirmala et al., 2009), but in contrast to the syn conformation observed with respect to the meta-methyl groups in N-(3-methylphenyl)-benzenesulfonamide (III) (Gowda et al., 2010)
The molecule is twisted at the S atom with the C—SO2—NH—C torsion angle of -57.6 (2)°, compared to the values of 56.7 (3)° in (II), 55.8 (2)° (molecule 1) and -58.4 (3)° (molecule 2) in the two molecules of (III), and -53.8 (3)° and -63.4 (3)° in the two independent molecules of 4-chloro-N-(phenyl)-benzenesulfonamide (IV)(Shakuntala et al., 2011).
The sulfonyl and the anilino benzene rings are tilted relative to each other by 84.7 (1)° in (I), compared to the values of 83.9 (1)° in (II), 67.9 (1)° (molecule 1) and 68.6 (1)° (molecule 2) in (III), and 69.1 (1)° and 82.6 (1)° in the two independent molecules of (IV).
The packing of molecules in the crystal via intermolecular N—H···O hydrogen bonds (Table 1) is shown in Fig. 2.
