【 摘 要 】

In the title compound, C27H21FN2O4, the mean planes of the indole ring systems (r.m.s. deviations = 0.0263 and 0.0160 Å) are approximately perpendic­ular to one another, making a dihedral angle of 84.0 (5)°; the fluoro­benzene ring is twisted with respect to the mean planes of the two indole ring systems at 89.5 (5) and 84.6 (3)°. In the crystal, pairs of N—H⋯O hydrogen bonds link the mol­ecules into inversion dimers, which are further linked by N—H⋯O hydrogen bonds into supra­molecular chains propagated along the b-axis direction. Weak C—H⋯π inter­actions are observed between neighbouring chains.
