Crystal structure of diethyl 3,3′-[(2-fluorophenyl)methylidene]bis(1H-indole-2-carboxylate)
In the title compound, C29H25FN2O4, the mean planes of the two indole ring systems (r.m.s. deviations = 0.1392 and 0.0115 Å) are approximately perpendicular to one another, subtending a dihedral angle of 86.0 (5)°; the benzene ring is twisted with respect to the mean planes of the two indole ring systems by 83.3 (2) and 88.1 (4)°, respectively. In the crystal, pairs of N—H...O hydrogen bonds link the molecules into centrosymmetric dimers, which are further linked by N—H...O hydrogen bonds into supramolecular chains propagating along the  direction.
