5''-(2,4-Dichloro-benzyl-idene)-1'-(2,4-dichloro-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.

In the title compound, C(37)H(30)Cl(4)N(2)O(2), the pyridinone ring adopts a twisted half-chair conformation. In the octa-hydro-indolizine fused-ring system, the piperidine ring is in a chair conformation and the pyrrole ring is twisted about the C-N bond linking the five- and six-membered rings. The mol-ecular structure features an intra-molecular C-H⋯O inter-action and the crystal packing is stabilized by C-H⋯π inter-actions.
