title: 1'-Methyl-4'-(1-naphth-yl)-3''-(1-naphthyl-methyl-ene)acenaphthene-1-spiro-2'-pyrrolidine-3'-spiro-1''-cyclo-hexane-2,2''-dione.
abstract: In the title compound, C(42)H(33)NO(2), the six-membered cyclo-hexa-none ring adopts a slightly distorted chair conformation and the five-membered pyrrolidine ring is in an envelope conformation. The mol-ecular structure features four intra-molecular C-H⋯O inter-actions and an intra-molecular C-H⋯π inter-action. Furthermore, the crystal packing is stabilized by an inter-molecular C-H⋯O and three inter-molecular C-H⋯π inter-actions.
