(Received 4 December 2010; accepted 7 December 2010; online 11 December 2010)

In the title compound, C13H11Cl2NO2S, 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 a C—SO2—NH—C torsion angle of 64.3 (4)°. Furthermore, the conformation of the N—H bond and the meta-chloro group in the adjacent benzene ring are anti to each other. The two benzene rings are tilted relative to each other by 82.5 (1)°. In the crystal, mol­ecules are linked by pairs of N—H⋯O(S) hydrogen bonds, forming inversion dimers.

Comment top

As part of a study of the substituent effects on the crystal structures of N-(aryl)-arylsulfonamides (Gowda et al., 2009; Shakuntala et al., 2010; 2011), in the present work, the structure of N-(3,4-dichlorophenyl)-4-methylbenzenesulfonamide (I) has been determined. In (I), the conformation of the N—C bond in the C—SO2—NH—C segment has gauche torsions with respect to the S═O bonds (Fig. 1). The conformation of the N—H bond and the meta-chloro groups in the adjacent benzene ring are anti to each other.

The molecule is bent at the S atom with the C—SO2—NH—C torsion angle of 64.3 (4)°, compared to the values of 65.4 (2)° (molecule 1) and -61.7 (2)° (molecule 2) in N-(2,3-dichlorophenyl)-4- methylbenzenesulfonamide (II) (Shakuntala et al., 2010), 62.1 (2)° in N-(2,5-dichlorophenyl)-4-methylbenzenesulfonamide (III) (Shakuntala et al., 2011) and 69.3 (4)° in N-(3,5-dichlorophenyl)-4-methylbenzenesulfonamide (IV) (Gowda et al., 2009).

The benzene rings in the title compound are tilted relative to each other by 82.5 (1)°, compared to the values of 76.0 (1)° (molecule 1) and 79.9 (1)° (molecule 2) in (II), 67.8 (1)° in (III) and 79.6 (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 linked by of N—H···O(S) hydrogen bonds(Table 1) is shown in Fig. 2.

Experimental top

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 3,4-dichloroaniline 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 N-(3,4-dichlorophenyl)-4-methylbenzenesulfonamide 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.

Prism like light brown single crystals used in X-ray diffraction studies were grown in ethanolic solution by slow evaporation at room temperature.

Refinement top

The H atom of the NH group was located in a difference map and later restrained to the distance N—H = 0.86 (3) Å. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.96 Å A l l H atoms were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

Special details top

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.
