The molecule of the title compound, C13H12ClNO2S, is bent at the S atom with a C—SO2—NH—C torsion angle of −54.8 (2)°. The dihedral angle between the two aromatic rings is 71.6 (1)°. An intramolecular N—H⋯Cl hydrogen bond is observed. The features inversion-related dimers formed by pairs of N—H⋯O hydrogen bonds.

A solution of toluene (10 ml) in chloroform (40 ml) was treated dropwise with chlorosulfonic acid (25 ml) at 273 K. 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 benzenesulfonylchloride was treated with 2-chloroaniline in the stoichiometric ratio and boiled for 10 min. The reaction mixture was then cooled to room temperature and added to ice cold water (100 ml). The resultant solid 4-methyl-N-(2-chlorophenyl)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 IR and NMR spectra. Single crystals used in X-ray diffraction studies were grown by a slow evaporation of an ethanolic solution at room temperature.
The H atom of the NH group was located in a difference map and its positional parameters were refined [N-H = 0.83 (3) Å]. The other atoms were positioned with idealized geometry using a riding model [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. |

As part of a study of the effect of substituents on crystal structures of N-(aryl)-arylsulfonamides (Gowda et al., 2009; Nirmala et al., 2009), the crystal structure of N-(2-chlorophenyl)4-methylbenzenesulfonamide (I) has been determined. The conformation of the N—H bond is syn to the 2-chloro group in the aniline benzene ring. The molecule is bent at the S atom with a C1—S1—N1—C7 torsion angle of -54.8 (2)°, compared to the value of -51.6 (3)° in N-(phenyl)4-methylbenzenesulfonamide (II) (Gowda et al., 2009) and 60.0 (2)° in N-(2-methylphenyl)4-methylbenzenesulfonamide (III) (Nirmala et al., 2009).
The two benzene rings in (I) are tilted relative to each other by 71.6 (1)°, compared to 68.4 (1)° in (II) and 49.7 (1)° in (III). The other bond parameters are similar to those observed in (II), (III) and other aryl sulfonamides (Perlovich et al., 2006; Gelbrich et al., 2007).
The structure exhibits both the intramolecular N—H···Cl and the intermolecular N—H···O(S) hydrogen bonds.
In the crystal structure, pairs of intermolecular N—H···O hydrogen bonds (Table 1) link the molecules into inversion-related dimers. Part of the crystal structure is shown in Fig. 2.
