Key indicators: single-crystal X-ray study; T = 295 K; mean (C-C) = 0.003 Å; R factor = 0.055; wR factor = 0.176; data-to-parameter ratio = 26.6.In the title compound, C 25 H 19 FN 2 O 5 S, 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-HÁ Á ÁO hydrogen bonds. In the crystal, weak C-HÁ Á ÁO, C-HÁ Á ÁF and -[centroidcentroid distance = 3.6645 (11) Å ] interactions link the molecules, forming a three-dimensional network.
