摘要：
The N-C and C-C bond distances in the pyrrolizidine moiety of the title compound, C33H26N2O4, are slightly longer than the normal values. This is due to the steric forces caused by bulky substituents on the pyrrolizidine ring system. The acenaphthene ketone O atom is. 0.214 (3) Angstrom from the acenaphthene plane, while the indole ketone O atom is displaced by only 0.004 (3) Angstrom from the indole plane. The molecular structure is stabilized by intramolecular C-H...O interactions. The crystal packing is stabilized by C-H...O intermolecular interactions.
