The title compound was prepared according to the literature method (Jayalakshmi & Gowda, 2004). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra (Jayalakshmi & Gowda, 2004). Single crystals of the title compound were obtained from a slow evaporation of its ethanolic solution.
Methyl groups were refined as riding with C—H = 0.96Å and Uiso(H) = 1.2 Ueq(C). The coordinates of the remaining H atoms were refined with Uiso(H) = 1.2 Ueq(C,N).
The stereochemistry of biologically important alkyl sulfonanilides is of interest in explaining their biological activity. The biological activity may be due to N—H group. Therefore the structural studies of sulfonanilides are of interest. In the present work, the structure of N-(3-methylphenyl)-methanesulfonamde (3MPMSA) has been determined to explore the substituent effects on the structures of anilides and sulfonanilides (Gowda et al., 2000, 2007, 2007a,b). The conformation of the N—H bond in the structure of 3MPMSA, is anti to the meta-methyl substituent (Fig.1), similar to that observed in the corresponding meta- nitro substituted sulfonanilide (3NPMSA)(Gowda et al., 2007b). The bond parameters in the 3 compounds, PMSA (Klug, 1968), 3MPMSA and 3NPMSA are similar except in the S—N—C bond angle [120.0 (1)° (PMSA); 121.2 (2)° (3MPMSA); 126.3 (3)° (3NPMSA)] and in the S—N—C—C torsion angles [S2—N5—C6—C7 and S2—N5—C6—C11: 75.5 (2)° and -106.6 (2)° (PMSA); 68.1 (4)° and -114.3 (3)° (3MPMSA); 41.1 (3)°, -140.8 (2)° (3NPMSA)]. The molecules are linked in chains in the direction of c axis through N—H···O hydrogen bonds. (Table 1 and Fig. 2).

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. |
