3′-Benzoyl-1′-methyl-4′-phenyl-spiro[acenaphthyl-ene- 1(2H),2′-pyrrolidin]-2-one

Abstract

In the title compound, C29H23NO2, the pyrrolidine ring adopts a twisted conformation about one of the C - N bonds. The acenaphthone ring (r.m.s. deviation = 0.025 Å) lies almost perpendicular to the pyrrolidine ring [dihedral angle = 88.08 (8)°]. The dihedral angle between the phenyl rings is 88.12 (11)°. In the crystal structure, weak C - H⋯π inter-actions connect the mol-ecules.
