The solution of 1,3-dichlorobenzene (10 ml) in chloroform (40 ml) was treated drop-wise 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 2,4-dichlorobenzenesulfonylchloride was treated with a stoichiometric amount of p-chloroaniline and boiled for ten minutes. The reaction mixture was then cooled to room temperature and added to ice cold water (100 ml). The resultant solid 2,4-dichloro-N- (4-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 infrared and NMR spectra (Savitha & Gowda, 2006). The 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 refined with the distance restraint N–H = 0.86 (2) Å. The other H atoms were positioned with idealized geometry using a riding model [C–H = 0.93 Å]. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

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. |

In the present work, as part of a study of substituent effects on the structures of N-(aryl)arylsulfonamides (Gowda et al., 2009, 2010), the structure of 2,4-dichloro-N-(4-chlorophenyl)benzenesulfonamide (I) has been determined (Fig. 1). The molecule is twisted at the S—N bond with the C—SO2—NH—C torsion angle being 67.8 (2)° compared to the values of 60.6 (4)° (molecule 1), -59.7 (3)° (molecule 2), 63.9 (4)° (molecule 3) and 53.0 (4)° (molecule 4), in the four molecules of 2,4-dichloro-N- (4-methylphenyl)benzenesulfonamide (II) (Gowda et al., 2010) and -48.2 (2)° in 2,4-dichloro-N-(3,4-dichlorophenyl)benzenesulfonamide (III) (Gowda et al., 2009).
The sulfonyl benzene and the aniline benzene rings in (I) are tilted relative to each other by 65.0 (1)°, compared to the values of 85.2 (1)° (molecule 1), 80.5 (2)° (molecule 2, disordered orientation A), 80.1 (2)° (molecule 2, orientation B), 87.5 (7) (molecule 3, disordered orientation A), 87.0 (6)° (molecule 3, orienation B) and 72.4 (1)° (molecule 4) in the four molecules of (II) and 68.9 (1)° in (III). The other bond parameters in (I) are similar to those observed in (II), (III) and other aryl sulfonamides (Perlovich et al., 2006; Gelbrich et al., 2007).
In the crystal structure, the pairs of intermolecular N—H···O hydrogen bonds (Table 1) link the molecules to form inversion-related dimers as shown in Fig. 2.
