5''-(2-Fluoro-benzyl-idene)-1'-(2-fluoro-phen-yl)-1''-methyl-1',2',3',5',6',7',8',8a'-octa-hydro-dispiro-[ace-naphthyl-ene-1,3'-indolizine-2',3''-piperidine]-2,4''(1H)-dione.

ABSTRACT: In the title compound, C37H32F2N2O2, the central six-membered piperidine ring adopts a twisted half-chair conformation, with the N and methyl-ene C atoms deviating by -0.2875 (16) and 0.4965 (15) Å, respectively, from the mean plane defined by the other four atoms. The piperidine connected to the octa-hydro-indolizine ring is in a half-chair conformation. The five-membered pyrrole ring adopts a slightly twisted envelope conformation with the piperidine C atom as the flap atom. The F and H atoms of both fluoro-benzene rings are disordered, with occupancy factors of 0.941 (3):0.059 (3) and 0.863 (3):0.137 (3). The mol-ecular structure features some intra-molecular C-H⋯O inter-actions. In the crystal, a supra-molecular zigzag chain sustained by C-H⋯F inter-actions parallel to the c axis is formed, generating a C(12) graph-set motif.
