Diethyl 3,3′-[(3-fluorophenyl)methylene]bis(1H-indole-2-carboxylate)

Abstract

In the title compound, C29H25FN2O4, the mean planes of the indole ring systems are approximately perpendicular to one another [dihedral angle = 88.3 (4)°]. The benzene ring is twisted with respect to the indole ring systems by 49.8 (5) and 77.6 (3)°. In the crystal, pairs of N—H...O hydrogen bonds link the molecules into the inversion dimers which are further linked into supramolecular chains propagating along the [110] direction.
