S1. Comment

Diaryl acylsulfonamides are known as potent antitumor agents against a broad spectrum of human tumor xenografts in nude mice. As part of our studies on the substituent effects on the structures and other aspects of N-(aryl)-amides (Bowes et al., 2003; Gowda et al., 1999, 2003), N-(aryl)-methanesulfonamides (Gowda et al., 2007), N-(aryl)-arylsulfonamides (Shetty & Gowda, 2005); N-(substitutedbenzoyl)-arylsulfonamides (Suchetan et al., 2012); N-chloroarylsulfonamides (Jyothi & Gowda, 2004) and N-bromoarylsulfonamides (Usha & Gowda, 2006), in the present work, the crystal structure of N-(2-chlorobenzoyl)-3-nitrobenzenesulfonamide (I) has been determined (Fig.1).

The conformation between the N—H and C═O bonds in the C—SO₂—NH—C(O) segment is anti and the N—C bond in the segment has gauche torsion with respect to the S═O bonds (Fig. 1), similar to that observed in N-(3-chlorobenzoyl)-3-nitrobenzene-sulfonamide (II) (Suchetan et al., 2012). Further, in (I), the conformation between the N—H bond and the meta-nitro group in the sulfonyl benzene ring is syn, similar to that observed in (II). The conformation of the C═O is also syn to the ortho-Cl atom in the benzoyl ring, in contrast to the anti conformation observed between the C═O and the meta-Cl atom in (II)

The molecule is twisted at the S—N bond with the torsional angle of -61.82 (29)°, compared to the value of -60.40 (29)° in (II).

The dihedral angle between the sulfonyl benzene ring and the —SO₂—NH—C—O segment is 80.4 (1)°, compared to the value of 77.0 (1)° in (II). Furthermore, the dihedral angle between the sulfonyl and the benzoyl benzene rings is 84.3 (1)°, compared to the value of 83.5 (1)° in (II).

The packing of molecules linked by of N—H···O(S) hydrogen bonds (Table 1) is shown in Fig. 2.

S2. Experimental

The title compound was prepared by refluxing a mixture of 2-chlorobenzoic acid (0.02 mole), 3-nitrobenzenesulfonamide (0.02 mole) and excess phosphorous oxychloride for 3 h on a water bath. The resultant mixture was cooled and poured into crushed ice. The solid, N-(2-chlorobenzoyl)-3-nitrobenzenesulfonamide, 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. It was filtered, dried and recrystallized.

Rod like colourless single crystals of the title compound used in X-ray diffraction studies were obtained by slow evaporation of its toluene solution at room temperature.

S3. Refinement

The H atom of the NH group was 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 Å. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the U_eq 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.
