In the title compound, C₂₅H₁₉FN₂O₅S, the substituted phenyl ring makes a dihedral angle of 12.26 (9)° with the indole ring system. The nitro group is twisted at an angle of 26.92 (8)° out of the plane of the ring to which it is attached. The molecular structure is stabilized by weak C—H⋯O hydrogen bonds. In the crystal, weak C—H⋯O, C—H⋯F and π–π [centroid–centroid distance = 3.6645 (11) Å] interactions link the molecules, forming a three-dimensional network.

Comment top

Indole derivatives are known to exhibit antimicrobial, antibiotic, analgesic, anticancer and anti-HIV (Pomarnacka & Kozlarska-Kedra, 2003; Srivastava et al., 2011) activities. In continuation of our studies on indole derivatives, we determined the crystal structure of the title compound (I). The geometric parameters of (I) (Fig. 1) are agree well with the reported structures (Chakkaravarthi et al., 2008; 2010).

Due to Thorpe-Ignold effect (Bassindale, 1984), bond angles around atom S1 show significant deviation from ideal tetrahedral value, with significant deviations in angles O1—S1—O2 [120.42 (8)°] and N1—S1—C1 [104.66 (7)°]. The phenyl ring (C1—C6) makes the dihedral angle of 85.05 (8)° with the indole ring system. The phenyl ring (C1—C6) and the benzene ring (C20—C25) are inclined at an angle of 12.26 (9)°. The nitro group is twisted at an angle of 26.92 (8)° with the attached benzene ring (C20—C25). The sum of the bond angles around N1 (358.26°) indicates the sp² hybridization of N1 atom (Beddoes et al., 1986).

The molecular structure is stabilized by weak intramolecular C—H···O hydrogen bonds (Table 1). The crystal structure exhibit weak intermolecular C—H···O, C—H···F (Table 1 & Fig. 2) and π···π [Cg4···Cg4ⁱ = 3.6645 (11) Å; (i) 1 - x, -1 - y, 2 - z; Cg4 is the centroid of the ring (C20—C25)] interactions.

Experimental top

A solution of 1-(2-(bromomethyl)-1-(phenylsulfonyl)-1H-indol-3-yl) propan-1-one (5 g, 12.31 mmol) and triphenylphosphine (3.5 g, 13.54 mmol) in dry THF (100 ml) was refluxed for 6 h. After consumption of the starting material, the solvent was removed under vacuo and the solid was washed with diethyl ether to give the phosphonium salt. Then, the mixture of phosphonium salt (8 g, 11.97 mmol), 4-fluoro-2-nitrobenzaldehyde (2.24 g, 13.17 mmol) and K₂CO₃ (3.30 g, 23.95 mmol) in DCM (70 ml) was stirred at room temperature for 22 h. After completion of the reaction (monitored by TLC), it was diluted using DCM (30 ml), washed with water (2 x 100 ml) and dried (Na₂SO₄). Removal of solvent in vacuo followed by trituration of the crude product with MeOH (20 ml) afforded the title compound suitable for X-ray diffraction quality.

Special details top

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.
