The title compound was prepared by refluxing benzenesulfonamide (0.10 mole) with an excess of acetyl chloride (0.20 mole) for about an hour on a water bath. The reaction mixture was cooled and poured into ice cold water. The resulting solid was separated, washed thoroughly with water and dissolved in warm dilute sodium hydrogen carbonate solution. The title compound was reprecipitated by acidifying the filtered solution with glacial acetic acid. It was filtered, dried and recrystallized from ethanol. The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared spectra.
Rod like colorless single crystals were obtained from a slow evaporation of an ethanolic solution of the compound.
The H atom of the NH group was located in a difference map. Its coordinates were refined with a distance restraint of N—H = 0.86 (2) Å. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.96 Å. All H atoms were refined with isotropic displacement parameters set to 1.2 times of the Ueq of the parent atom.
Sulfonamide drugs contain the sulfanilamide moiety (Maren, 1976). The propensity for hydrogen bonding in the solid state, due to the presence of various hydrogen bond donors and acceptors can give rise to
(Yang & Guillory, 1972). The hydrogen bonding preferences of has also been investigated (Adsmond & Grant, 2001). The nature and position of substituents play a significant role on the crystal structures of N-(aryl)sulfonoamides (Gowda et al., 2008a,b, 2009). As a part of studying the substituent effects on the structures of this class of compounds, the structure of N-(phenylsulfonyl)-acetamide (I) has been determined. The conformations of the N—H and C=O bonds of the SO2—NH—CO—C segment in the structure are anti to each other (Fig. 1), similar to that observed in N-(phenylsulfonyl)-2,2-dimethylacetamide (II)(Gowda et al., 2009), N-(phenylsulfonyl)-2,2,2- trimethylacetamide (III)(Gowda et al., 2008b) and N-(phenylsulfonyl)-2,2-dichloroacetamide (IV) (Gowda et al., 2008a).The C7—N1 bond in the C—SO2—NH—C segment of (I) is gauche [C7—N1—S1—O2 = 58.3 (5)°] with respect to the S1═O1 bond and anti with respect to the S1═O2 bond [C7—N1—S1—O1 = -172.6 (4)°]. The molecule in (I) is bent at the S-atom with a C1—S1—N1—C7 torsion angle of -58.8 (4)°, compared to the value of 67.1 (3)° in (II) and -66.3 (3)° in (IV),
The packing of molecules linked by N—H···O hydrogen bonds (Table 1) is shown in Fig. 2.

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

Sulfonamide drugs contain the sulfanilamide moiety (Maren, 1976). The propensity for hydrogen bonding in the solid state, due to the presence of various hydrogen bond donors and acceptors can give rise to polymorphism (Yang & Guillory, 1972). The hydrogen bonding preferences of sulfonamides has also been investigated (Adsmond & Grant, 2001). The nature and position of substituents play a significant role on the crystal structures of N-(aryl)sulfonoamides (Gowda et al., 2008a,b, 2009). As a part of studying the substituent effects on the structures of this class of compounds, the structure of N-(phenylsulfonyl)-acetamide (I) has been determined. The conformations of the N—H and C=O bonds of the SO2—NH—CO—C segment in the structure are anti to each other (Fig. 1), similar to that observed in N-(phenylsulfonyl)-2,2-dimethylacetamide (II)(Gowda et al., 2009), N-(phenylsulfonyl)-2,2,2- trimethylacetamide (III)(Gowda et al., 2008b) and N-(phenylsulfonyl)-2,2-dichloroacetamide (IV) (Gowda et al., 2008a).
The C7—N1 bond in the C—SO2—NH—C segment of (I) is gauche [C7—N1—S1—O2 = 58.3 (5)°] with respect to the S1═O1 bond and anti with respect to the S1═O2 bond [C7—N1—S1—O1 = -172.6 (4)°]. The molecule in (I) is bent at the S-atom with a C1—S1—N1—C7 torsion angle of -58.8 (4)°, compared to the value of 67.1 (3)° in (II) and -66.3 (3)° in (IV),
The packing of molecules linked by N—H···O hydrogen bonds (Table 1) is shown in Fig. 2.
