In the title compound, C27H22N2O4, the two indole ring systems are approximately perpendicular to each other, with a dihedral angle of 84.5 (5)° between their planes; the benzene ring is twisted with respect to the two indole ring systems at angles of 78.5 (5) and 86.5 (3)°. In the crystal, molecules are linked by N—HO hydrogen bonds, weak C—HO and C—HN hydrogen bonds, and C—Hπ interactions into a three-dimensional supramolecular architecture.
