title: (4S)-4-(3,4-Dichloro-phen-yl)-1'-methyl-4'-phenyl-3,4-dihydronaphthalene-2-spiro-3'-pyrrolidine-2'-spiro-1''-acenaphthyl-ene-1,2''(2H,1''H)-dione.
abstract: In the title compound, C(37)H(27)Cl(2)NO(2), the 3,4-dichloro-phenyl ring makes a dihedral angle of 46.66 (6)° with the phenyl ring. The mol-ecular structure is stabilized by weak intra-molecular C-H⋯O inter-actions and the crystal structure is stabilized by weak inter-molecular C-H⋯O inter-actions. The C-C-C-C-C five-membered ring is planar, while the C-C-C-C-N five-membered ring adopts a half-chair conformation.
