In the title compound, C11H16N2O3S, the S atom has a distorted tetrahedral geometry [maximum deviation: O—S—O = 119.48 (15)°]. The dihedral angles between the benzene ring and its propylsulfonamide and methylamide substituents are 71.8 (2) and 5.8 (1)°, respectively. In the crystal, molecules are linked by Nm—H⋯Os (m = methylamide and s = sulfonamide) hydrogen bonds, forming C(8) chains along the a axis. The two molecule chains are connected by N—H⋯O hydrogen bonds, generating R32(18) rings. The crystal packing is further stabilized by weak intermolecular C—H⋯O hydrogen bonds.

10 mM of 4-acetamido benzene sulfonyl chloride was taken in the reaction flask and about 20 ml distilled water was added in it. Mixed it well. Then 10 mM of propylamine hydrochloride was added in it. 3% Na2CO3 was used to maintain the pH at 8–10. The reaction was stirred for about 2 h to get the maximum yield. Precipitates obtained was filtered and dried. They are recrystallized in the mixture of methanol and ethyl acetate 1:1. The reaction was monitored by TLC.
The N-bound H atoms were located in difference Fourier maps and isotropically refined with the N–H distance restraint [0.86 (1) Å)]. The C-bound H atoms were geometrically placed using a riding model with C—H = 0.93 - 0.97 Å, and Uiso(H)= 1.2Ueq(Caromatic, Cmethylene) and Uiso(H) = 1.5Ueq(Cmethyl).

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. |

Sulfonamides are derivatives of p-aminobenzene sulfonic acid (Ahrens, 1996) belong to the oldest group of antibiotics which are also being used now-a-days. These are white crystalline powder derived from azo dye (Adams, 2001) and have weak organic acid characteristics with a structural resemblance to p-aminobenzoic acid which is an intermediate required for the synthesis of folic acid in bacteria (Ahrens, 1996). The sensitivity of sulfonamides is dependent on the mode in which organisms fulfill their folic acid requirements. Sulfonamides are considered as bacteriostatic drugs (Mayers, 2009 & Betts et al., 2003) which are used for the treatment of systematic infections and are absorbed in the gastrointestinal tract (Root, 1999).
As part of our ongoing studies (Faryal et al., 2011, Ahmad et al. (2011a,b), we synthesized the title compound, (I), and report herein its crystal structure.
In the title compound, (Fig. 1), the dihedral angles between the benzene ring (C4—C9) and the propylsulfonamide (C1,C2,C3,N1,S1) and methylamide (N2,C10,O3,C11) moieties are 71.8 (1) and 5.8 (1)°, respectively. The S atom has a distorted tetrahedral geometry [maximum deviation: O—S—O = 119.48 (15)°]. The C—S—N—C torsion angles are 66.1 (2)°.
In the crystal, the molecules are linked by Nm—H···Os (m = methylamide, s = sulfonamide) hydrogen bonds, forming C(8) chains along the a axis (Table1, Fig. 2). The two molecule chains also connect by N—H···O hydrogen bonds, generating R32(18) rings (Bernstein et al., 1995; Etter et al., 1990; Motherwell et al., 1999; Table 1, Fig. 2). The crystal packing is further stabilized by the intermolecular C—H···O hydrogen bonds.
