3′′-(2-Fluorobenzylidene)-4′-(2-fluorophenyl)-1′-methyldispiro[acenaphthylene-1,2′-pyrrolidine-3′,1′′-cyclopentane]-2,2′′-dione

Abstract

In the title compound, C33H25F2NO2, the acenaphthene ring system forms dihedral angles of 50.93 (14) and 36.89 (14)° with the benzene rings. The pyrrolidine and cyclopentanone rings adopt envelope (with the N atom as the flap) and twisted conformations, respectively. In the crystal, C—H...O and C—H...F interactions link the molecules.
