(Received 6 June 2013; accepted 7 June 2013; online 12 June 2013)

In the title compound, C13H9ClN2O5S, the dihedral angle between the benzene rings is 74.86 (11)°. The mol­ecule is twisted at the S atom, with a dihedral angle of 82.53 (13)° between the sulfonyl benzene ring and the S—N—C=O segment. In the crystal, mol­ecules are linked into inversion dimers through pairs of N—H⋯O hydrogen bonds, thereby forming R22(8) loops. Mol­ecules are linked into C(7) [010] chains by weak C—H⋯O hydrogen bonds, and C—H⋯π inter­actions are also observed.

Comment top

Diaryl acylsulfonamides are known as potent anti-tumor agents against a broad spectrum of human tumor xenografts (colon, lung, breast, ovary, and prostate) in nude mice. As part of our studies in this area, the structure of the title compound, (I), was determined.

In the title compound, C13H9ClN2O5S (I), the conformation of the N—H bond in the C—SO2—NH—C(O) segment is anti to the C=O bond. In the molecule, the conformation between the N—H bond and the ortho-chloro group in the sulfonyl benzene ring is syn. Similarly, the conformation between the N—H bond and the meta-nitro group in the benzoyl ring is syn. The dihedral angle between the two benzene rings is 74.86 (11)°, compared to the value of 80.3 (1)° in N-(benzoyl)-benzenesulfonamide (Gowda et al. 2009), 86.9 (2)o N-(3-nitrobenzoyl)-benzenesulfonamide (Suchetan et al. 2012), 73.3 (1)° in N-benzoyl-2-chlorobenzenesulfonamide (Gowda et al. 2010) and 85.4 (1)o in 2-chloro-N-(4-nitrobenzoyl)benzenesulfonamide (Suchetan et al. 2011). In the crystal, the molecules are linked into inversion dimers through N—H···O hydrogen bonds forming a R22(8) motif. The molecules are further linked along [010] through a weak C—H···O intermolecular interaction into C(7) chains. C—H···Cg (where Cg is the centroid of the nitrobenzene ring) interactions are also observed in the crystal structure.

Experimental top

The title compound was prepared by refluxing a mixture of 3-nitrobenzoic acid, 2-chlorobenzene sulfonamide and phosphorous oxy chloride for 2 h on a water bath. The resultant mixture was cooled and poured into ice cold water. The Solid obtained was filtered and 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 solid was recrystallized to the constant melting point (483 K).

Colorless prisms of (I) were obtained from a slow evaporation of its ethanolic solution at room temperature.

Refinement top

The H atom of the NH group was located in a difference map and later restained to N—H = 0.81 (2) Å. 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 Ueq of the parent atom).

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
