In the title molecule, C29H29N5, the indole ring systems are essentially planar, with maximum deviations of 0.020 (2), 0.023 (2) and 0.016 (2) Å. The dihedral angles formed between the mean planes of the three indole ring systems are 38.08 (7), 89.64 (8) and 58.28 (8)°. In the crystal, molecules are connected by N-HN hydrogen bonds, forming inversion dimers. An intramolecular N-HN hydrogen bond is also observed.
