title: 4-Ferrocenyl-1-methyl-3-benzoyl-spiro-[pyrrolidine-2,11'-indeno-[1,2-b]quinoxaline].
abstract: In the title compound, [Fe(C5H5)(C31H24N3O)], the pyrrolidine ring adopts a twist conformation. The pyrrolidine ring is almost perpendicular to the indeno-quinoxaline ring system, making a dihedral angle of 84.44 (5)°. The cyclo-penta-dienyl rings of the ferrocene moiety adopt an eclipsed conformation. The crystal packing features weak C-H⋯N and C-H⋯π inter-actions.
