(Received 18 June 2010; accepted 20 June 2010; online 26 June 2010)

In the title compound, C13H9Cl2NO3S·H2O, the conformation of the C=O bond is syn to the meta-Cl group in the benzoyl ring. The mol­ecules are twisted at the S—N bond with a C—S—N—C torsion angle of 72.9 (2)°. The dihedral angle between the sulfonyl benzene ring and the S—NH—C—O segment is 77.8 (1)° and that between the sulfonyl and benzoyl benzene rings is 80.5 (1)°. In the crystal, mol­ecules are linked into a two-dimensional network parallel to (100) by N—H⋯O and O—H⋯O hydrogen bonds.

Comment top

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., 2009, 2010; Suchetan et al., 2010a,b), the structure of 4-chloro-N-(3-Chlorobenzoyl)benzenesulfonamide monohydrate (I) has been determined (Fig.1).

The conformation of the N—H bond in the C—SO2—NH—C(O) segment is anti to the C═O bond, similar to those observed in N-(3-chlorobenzoyl)-benzenesulfonamide (II) (Gowda et al., 2009), N-(benzoyl)-4-chlorobenzenesulfonamide (III) (Suchetan et al., 2010a), 4-chloro-N-(2-chlorobenzoyl)benzenesulfonamide (IV) (Gowda et al., 2010), and N-(4-chlorobenzoyl)-4- chlorobenzenesulfonamide (V) (Suchetan et al., 2010b).

Further, the conformation of the C═O bond in the C—SO2—NH—C(O) segment of (I) is syn to the meta-Cl in the benzoyl ring, similar to that observed between the C═O bond and ortho-Cl in (IV), but contrary to the anti conformation observed between the C═O bond and meta-Cl in (II).

The molecules are twisted at the S—N bond with the C1—S1—N1—C7 torsional angle of 72.9 (2)°, compared to those of 65.3 (2)° in (II), -70.0 (2)°, 61.3 (2)° in the two independent molecules of (III), 65.7 (2)° in (IV) and 67.5 (3)° in (V).

The dihedral angles between the sulfonyl benzene ring and the S/N/C/O plane is 77.8 (1)°, compared to the values of 89.9 (1)° in (II), 72.0 (1)° & 77.3 (1)° in the two molecules of (III), 88.5 (1)° in (IV) and 79.0 (1)° in (V).

Furthermore, the dihedral angle between the sulfonyl and the benzoyl benzene rings is 80.5 (1)°, compared to the values of 87.5 (1)° in (II), 62.8 (1)° (molecule 1) and 78.6 (1)° (molecule 2) of (III), 58.0 (1)° in (IV) and 85.6 (1)° in (V)

The molecules are linked into a two-dimensional network (Fig.2) parallel to the (100) by N—H···O and O—H···O hydrogen bonds (Table 1).

Experimental top

The title compound was prepared by refluxing a mixture of 3-chlorobenzoic acid, 4-chlorobenzenesulfonamide and phosphorous oxy chloride for 3 h on a water bath. The resultant mixture was cooled and poured into ice cold water. The solid 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. Long needle 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.

Refinement top

The H atom of the NH group and the H atoms of the water molecule were located in a difference map and later restrained to N–H = 0.86 (2) %A and to O–H = 0.85 (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 Ueq of the parent atom).

Special details top

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.
