(Received 29 November 2011; accepted 1 December 2011; online 7 December 2011)

In the title compound, C14H12ClNO3S·H2O, the dihedral angle between the sulfonyl and benzoyl benzene rings is 84.4 (2)°. In the crystal, every water mol­ecule forms four hydrogen bonds with three different mol­ecules of 4-chloro-N-(3-methyl­benzo­yl)benzene­sulfonamide. One of the water H atoms forms a bifurcated hydrogen bond with both the sulfonyl and the carbonyl O atoms of the same mol­ecule. Mol­ecules are linked into layers in the ab plane through N—H⋯O and O—H⋯O hydrogen bonds.

Comment top

Diaryl acylsulfonamides are known as potent antitumor agents. As part of our studies on the substituent effects on the structures and other aspects of N-(aryl)-amides (Gowda et al., 2004), N-(aryl)-methanesulfonamides (Jayalakshmi & Gowda, 2004), N-(aryl)-arylsulfonamides (Gowda et al., 2003); N-(substitutedbenzoyl)-arylsulfonamides (Suchetan et al., 2011) and N-chloro-arylsulfonamides (Gowda et al., 1996), in the present work, the crystal structure of 4-Chloro-N-(3-methylbenzoyl)-benzenesulfonamide monohydrate (I) has been determined (Fig.1).

The conformations of the N—H and C=O bonds in the C—SO2—NH—C(O) segment are anti to each other (Fig.1), similar to that observed in 4-Chloro-N-(2-methylbenzoyl)-benzenesulfonamide monohydrate (II) (Suchetan et al., 2011). The molecule is twisted at the S- atom with the torsional angle of -70.67 (55)°, compared to the value of -69.2 (2)° in (II).

The dihedral angle between the sulfonyl benzene ring and the —SO2—NH—C—O segment is 78.4 (2)°, compared to the value of 87.2 (1)° in (II). Furthermore, the dihedral angle between the sulfonyl and the benzoyl benzene rings is 84.4 (2)°, compared to the value of 57.7 (1)° in (II).

Further, the crystal structure shows interesting H-bonding. Every water molecule forms four H-bonds with three different molecules of the title compound. One of the H-atoms of the water molecule forms simultaneous H-bonding with both the sulfonyl and the carbonyl oxygen atoms of the same molecule.

The packing of molecules through N1—H1N···O4, O4—H41···O1, O4—H41···O3 and O4—H42···O2 hydrogen bonds (Table 1) is shown in Fig. 2.

Experimental top

The title compound was prepared by refluxing a mixture of m-methyl benzoic acid (0.02 mole), 4-chlorobenzenesulfonamide (0.02 mole) and excess phosphorous oxy chloride for 3 h on a water bath. The resultant mixture was cooled and poured into crushed ice. The solid, 4-Chloro-N-(3-methylbenzoyl)-benzenesulfonamide monohydrate, 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.

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

Refinement top

The H atoms of the NH group and of the water molecule were located in a difference map and later restrained to N—H = 0.86 (2)Å and O—H = 0.85 (2) Å. The other H atoms were positioned with idealized geometry using a riding model with the aromatic C—H = 0.93 Å and methyl C—H = 0.96 Å. All H atoms were refined with isotropic displacement parameters set to 1.2 times of the Ueq of the parent atom.

Experimental. CrysAlis RED (Oxford Diffraction, 2009) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

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.
