In the title compound, C22H16BrNO3S, the phenyl rings make dihedral angles of 84.81 (16) and 61.67 (17)° with the indole ring system (r.m.s. deviation = 0.012 Å), while the phenyl rings are inclined to one another by 69.5 (2)°. The molecular structure is stabilized by weak intramolecular C—H⋯O hydrogen bonds. The sulfonyl S atom has a distorted tetrahedral configuration. In the crystal, there are no significant intermolecular interactions present.

To a solution of (2-methyl-1-(phenylsulfonyl)-1H-indol-3-yl)(phenyl)methanone (1 g, 2.67 mmol) in dry carbon tetrachloride (75 mL), AIBN (0.05 g) and finely powdered NBS (0.61 g, 3.47 mmol) were added. The reaction mixture was refluxed for 2 h and cooled to room temperature. The floated succinimide was filtered off and washed with carbon tetrachloride (15 mL). The combined filtrate was concentrated in vacuo to afford title compound (1.12 g, 92%) as a colourless solid (156-158°C), suitable for X-ray diffraction.
Crystal data, data collection and structure
details are summarized in Table 2. C-bound H atoms were included in calculated positions and treated as riding atoms: C—H = 0.93 - 0.97 Å with Uiso(H) = 1.5Ueq(C) for methyl H atoms and = 1.2Ueq(C) for other H atoms.Indole derivatives are known to exhibit antibacterial, antifungal (Singh et al., 2000), antitumour (Andreani et al., 2001), antidepressant (Grinev et al., 1984), anti-inflammatory (Rodriguez et al., 1985) and physiological (Porter et al., 1977; Sundberg, 1996) properties. In recent years, we have reported the synthesis and crystal structures of a number of such compounds (Chakkaravarthi et al., 2008, 2009; Umadevi et al., 2013, 2014). We report herein on the synthesis and
of the title compound, a new 1-(phenylsulfonyl)-1H-indole derivative.The molecular structure of the title compound is shown in Fig. 1. The phenyl rings (C1—C6) and (C17—C22) make the dihedral angles of 84.81 (16)° and 61.67 (17)°, respectively, with the indole ring system (N1/C7—C14). The phenyl rings (C1—C6) and (C17—C22) are inclined at an angle of 69.5 (2)° with respect to each other. As a result of electron–withdrawing character of the phenylsulfonyl group, the bond lengths N1—C7 = 1.415 (4) Å and N1—C14 = 1.409 (4) Å are longer than the mean value of 1.355 (14) Å observed for similar compounds in the Cambridge Structural Database (Groom & Allen et al., 2014). Atom S1 of the sulfonyl group has a distorted tetrahedral configuration. The widening of angle O1—S1—O2 [120.70 (15)°] and the narrowing of angle N1—S1—C1 [104.71 (14)°] from the ideal tetrahedral value are attributed to the Thorpe–Ingold effect (Bassindale, 1984). The molecular structure is stabilized by weak C—H···O intramolecular hydrogen bonds (Table 1).
In the crystal, there are no significant intermolecular interactions present, 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. |
