In the acridine system of the title molecule, C26H30N2O 2, both cyclohex-2-enone rings adopt sofa conformations. The indole ring system is essentially planar, with a maximum deviation of 0.017 (2) Å for a bridgehead C atom. An intramolecular C-H⋯O hydrogen bond occurs. The molecules assemble into C(6) chains in the crystal by way of N-H⋯O hydrogen bonds.
