title: 5''-(4-Chloro-benzyl-idene)-1'-(4-chloro-phen-yl)-1''-methyl-1',2',3',5',6',7',8',8a'-octa-hydro-dispiro-[acenaphthyl-ene-1,3'-indolizine-2',3''-piperidine]-2,4''(1H)-dione.
abstract: In the title compound, C37H32Cl2N2O2, the pyridinone ring adopts a twisted half-chair conformation. The fused pyrrolidine and piperidine rings of the octa-hydro-indolizine unit exhibit envelope (with the C atom bound to the C atom bearing the chloro-benzene ring being the flap atom) and chair conformations, respectively. The dihedral angle between the chloro-benzene rings is 84.03 (1)°. In the crystal, C-H⋯π inter-actions lead to supra-molecular chains along [101] that assemble in the ac plane. Connections along the b axis are of the type Cl⋯Cl [3.4065 (8) Å].
