Abstract: In the title compound, C33H29NO4, the acenaphthylene ring system is essentially planar (r.m.s. deviation = 0.0290 Å). The pyrrolidine ring adopts a C-envelope conformation with a C atom displaced by 0.671 (2) Å from the mean-plane formed by the remaining ring atoms. The pyrrolidine ring is fused to acenaphthylene ring system making a dihedral angle of 88.0 (7)°. In the crystal, molecules are linked into R22(9) dimers via C-H...N and C-H...O hydrogen bonds. Two C atoms act as donors to the same O atom acceptor, resulting in the formation of R21(7) ring motifs. These two motifs combine to form hydrogen-bonded sheets running along the a- and b-axis directions.
