【 摘 要 】

In the title compound, C27H21FN2O4, the mean planes of the two indole ring systems (r.m.s. deviations = 0.0166 and 0.0086 Å) are approximately perpendicular to one another, making a dihedral angle of 87.8 (5)°; the fluorobenzene ring is twisted with respect to the mean planes of the two indole ring systems at 82.7 (5) and 85.5 (3)°. In the crystal, pairs of N—H...O hydrogen bonds link the molecules into the inversion dimers, which are further linked by N—H...O hydrogen bonds into supramolecular chains propagating along the b-axis direction. Weak C—H...π interactions are observed between neighbouring chains.
