In the title compound, C14H12ClNO3S, the conformation of the N—H bond in the C—SO2—NH—C(O) segment is anti to the C=O bond. The dihedral angle between the sulfonyl benzene ring and the —SO2—NH—C—O segment is 89.4 (1)° and that between the sulfonyl and benzoyl benzene rings is 89.1 (2)°. The features inversion-related dimers linked by pairs of N—H⋯O hydrogen bonds.

The title compound was prepared by refluxing a mixture of 4-methylbenzoic acid, 2-chlorobenzenesulfonamide and phosphorous oxy chloride for 5 h on a water bath. The resultant mixture was cooled and poured into ice cold water. The solid, 2-chloro-N-(4-methylbenzoyl)benzenesulfonamide obtained was filtered, washed thoroughly with water and then dissolved in sodium bicarbonate solution. The compound was later reprecipitated by acidifying the filtered solution with dilute HCl. The filtered and dried compound was recrystallized to the constant melting point.
Prism like colorless single crystals of the title compound used in X-ray diffraction studies were grown from a slow evaporation of its toluene solution at room temperature.
The H atoms of the NH groups were located in a difference map and later restrained to N—H = 0.86 (2) %A. The other H atoms were positioned with idealized geometry using a riding model with 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). The Uij components of C4, C9 and C10 atoms were restrained to approximate isotropic behavior.
Diaryl acylsulfonamides are known as potent antitumor agents against a broad spectrum of human tumor xenografts in nude mice. As a part of studying the effect of ring and the side chain substituents on the crystal structures of N-aromatic
(Gowda et al., 2010a,b; Suchetan et al., 2010a,b), the structure of 2-chloro-N-(4-methylbenzoyl)benzenesulfonamide (I) has been determined (Fig.1). The conformations of the N—C bonds in the C—SO2—NH—C(O) segments have gauche torsions with respect to the SO bonds. Further, the conformation of the N—H bond in the C—SO2—NH—C(O) segment is anti to the C=O bond, similar to that observed in 2-methyl-N-(4-methylbenzoyl)-benzenesulfonamide (II) (Gowda et al., 2010a), 2-chloro-N-(3-methylbenzoyl)-benzenesulfonamide (III) (Suchetan et al., 2010b), 2-chloro-N-(2-methylbenzoyl)- benzenesulfonamide (IV) (Suchetan et al., 2010a) and 2-chloro-N-(benzoyl)-benzenesulfonamide (V) (Gowda et al., 2010b).The molecules are twisted at the S atom with the torsional angle of 60.4 (3)°, compared to those of -53.1 (2)° and 61.2 (2)°, in the two molecules of (II), -66.5 (2)° in (III), -64.0 (2)° in (IV) and 66.7 (2)° in (V). The dihedral angle between the sulfonyl benzene ring and the —SO2—NH—C—O segment is 89.4 (1)°, compared to the values of 86.0 (1)° and 87.9 (1)° in the 2 molecules of (II), 88.4 (1)° in (III), 84.8 (1)° in (IV) and 87.3 (1)° in (V).
Furthermore, the dihedral angle between the sulfonyl and the benzoyl benzene ring is 89.1 (2)°, compared to the values of 88.1 (1)° (molecule 1) and 83.5 (1)° (molecule 2) of (II), 74.7 (1)° in (III), 78.7 (1)° in (IV) and 73.3 (1)° in (V).
The packing of molecules linked by of N—H···O(S) hydrogen bonds (Table 1) is shown in Fig. 2.

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. |

Diaryl acylsulfonamides are known as potent antitumor agents against a broad spectrum of human tumor xenografts in nude mice. As a part of studying the effect of ring and the side chain substituents on the crystal structures of N-aromatic sulfonamides (Gowda et al., 2010a,b; Suchetan et al., 2010a,b), the structure of 2-chloro-N-(4-methylbenzoyl)benzenesulfonamide (I) has been determined (Fig.1). The conformations of the N—C bonds in the C—SO2—NH—C(O) segments have gauche torsions with respect to the SO bonds. Further, the conformation of the N—H bond in the C—SO2—NH—C(O) segment is anti to the C=O bond, similar to that observed in 2-methyl-N-(4-methylbenzoyl)-benzenesulfonamide (II) (Gowda et al., 2010a), 2-chloro-N-(3-methylbenzoyl)-benzenesulfonamide (III) (Suchetan et al., 2010b), 2-chloro-N-(2-methylbenzoyl)- benzenesulfonamide (IV) (Suchetan et al., 2010a) and 2-chloro-N-(benzoyl)-benzenesulfonamide (V) (Gowda et al., 2010b).
The molecules are twisted at the S atom with the torsional angle of 60.4 (3)°, compared to those of -53.1 (2)° and 61.2 (2)°, in the two molecules of (II), -66.5 (2)° in (III), -64.0 (2)° in (IV) and 66.7 (2)° in (V). The dihedral angle between the sulfonyl benzene ring and the —SO2—NH—C—O segment is 89.4 (1)°, compared to the values of 86.0 (1)° and 87.9 (1)° in the 2 molecules of (II), 88.4 (1)° in (III), 84.8 (1)° in (IV) and 87.3 (1)° in (V).
Furthermore, the dihedral angle between the sulfonyl and the benzoyl benzene ring is 89.1 (2)°, compared to the values of 88.1 (1)° (molecule 1) and 83.5 (1)° (molecule 2) of (II), 74.7 (1)° in (III), 78.7 (1)° in (IV) and 73.3 (1)° in (V).
The packing of molecules linked by of N—H···O(S) hydrogen bonds (Table 1) is shown in Fig. 2.
