In the title compound, C13H12ClNO3S, the dihedral angle between the two aromatic rings is 73.94 (9)°. An intramolecular C—H⋯O hydrogen bond occurs. In the crystal, intermolecular N—H⋯O hydrogen bonds connect the molecules to centrosymmetric dimers, forming an R22(8) ring motif. The packing is consolidated by C—H⋯O hydrogen bonds and weak π–π interactions [centroid–centroid distances = 3.81 (3) and 3.81 (3) Å].

A mixture benzenesulfonyl chloride (10.0 mmol; 1.45 ml), 5-chloro-2-methoxy aniline (10.0 mmol; 1.47 g), aqueous sodium carbonate (10%; 20.0 ml) and water (25 ml) was stirred for one and half hour at room temperature. The crude mixture was washed with water and dried. The product was dissolved in methanol and recrystallized by slow evaporation of the solvent, to generate colourless crystal of N-(5-chloro-2-methoxyphenyl)benzenesulfonamide in 71% yield.
The amino H atom is located in a difference Fourier map and refined freely. The remaining H atoms were positioned geometrically (C—H = 0.93 and 0.96 Å) and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).
Sulfonamide is found in a number of synthetic as well as natural compounds. These molecules posses many biological activities e.g., herbicidal, anti-malarial, anti-convulsant and anti- hypertensive (Soledade et al., 2006; Xiao & Timberlake, 2000; Berredjem et al., 2000; Lee & Lee, 2002). In the present paper, the structure of N-(5-chloro-2-methoxyphenyl) benzenesulfonamide has been determined as part of a research program involving the synthesis and biological evaluation of sulfur containing compounds.
In the title molecule (I), (Fig. 1), both sulfonamido-O atoms lie on the opposite side of the S-bound phenyl ring to the sulfonamido-N1 atom [the O1–S1–C1–C6, O2–S1–C1–C2 and N1–S1–C1–C2 torsion angles are -34.32 (13), 14.43 (13) and -101.83 (12) °, respectively]. The dihedral angle formed between the phenyl (C1–C6) and benzene (C7–C12) rings in (I) is 73.94 (9) °.
The molecules of (I) are dimerized due to the intermolecular N—H···O hydrogen bonding (Table 1, Fig. 2) producing a R22(8) ring motif.
In addition, there are C—H···O hydrogen bonds, as well as π-π interactions [Cg1···Cg1(1 - x, -y, 2 - z) = 3.8163 (11) Å and cg2···Cg2(-x, 1 - y, 1 - z) = 3.9472 (12) Å; where Cg1 and Cg2 are centroids of the phenyl and benzene rings (C1–C6 and C7–C12), respectively], between the aromatic rings of each dimer.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

Sulfonamide is found in a number of synthetic as well as natural compounds. These molecules posses many biological activities e.g., herbicidal, anti-malarial, anti-convulsant and anti- hypertensive (Soledade et al., 2006; Xiao & Timberlake, 2000; Berredjem et al., 2000; Lee & Lee, 2002). In the present paper, the structure of N-(5-chloro-2-methoxyphenyl) benzenesulfonamide has been determined as part of a research program involving the synthesis and biological evaluation of sulfur containing compounds.
In the title molecule (I), (Fig. 1), both sulfonamido-O atoms lie on the opposite side of the S-bound phenyl ring to the sulfonamido-N1 atom [the O1–S1–C1–C6, O2–S1–C1–C2 and N1–S1–C1–C2 torsion angles are -34.32 (13), 14.43 (13) and -101.83 (12) °, respectively]. The dihedral angle formed between the phenyl (C1–C6) and benzene (C7–C12) rings in (I) is 73.94 (9) °.
The molecules of (I) are dimerized due to the intermolecular N—H···O hydrogen bonding (Table 1, Fig. 2) producing a R22(8) ring motif.
In addition, there are C—H···O hydrogen bonds, as well as π-π interactions [Cg1···Cg1(1 - x, -y, 2 - z) = 3.8163 (11) Å and cg2···Cg2(-x, 1 - y, 1 - z) = 3.9472 (12) Å; where Cg1 and Cg2 are centroids of the phenyl and benzene rings (C1–C6 and C7–C12), respectively], between the aromatic rings of each dimer.
