title: 7'-(Naphthalen-1-yl)-5''-[(naphthalen-2-yl)-methyl-idene]-1',3',5',6',7',7a'-hexa-hydro-dispiro-[acenaphthene-1,5'-pyrrolo-[1,2-c]thia-zole-6',3''-piperidine]-2(1H),4''-dione.
abstract: In the title compound, C(43)H(34)N(2)O(2)S, the six-membered piperidine ring adopts a half-chair conformation. The five-membered thia-zole ring adopts a slightly twisted envelope conformation and the pyrrole ring adopts an envelope conformation; in each case, the C atom linking the rings is the flap atom. The mol-ecular structure features inter- and intra-molecular C-H⋯O inter-actions. Furthermore, the crystal packing is stabilized by four inter-molecular C-H⋯π inter-actions.
