7′-[4-(Trifluoro­meth­yl)phen­yl]-5′,6′,7′,7a’-tetra­hydrodispiro­[indan-2,5′-pyrrolo­[1,2-c][1,3]thia­zole-6′,2′′-indan]-1,3,1′′-trione

In the title compound, C(29)H(20)F(3)NO(3)S, the thia­zolidine ringadopts a half-chair conformation. The pyrrolidine and two five-membered carbocyclic rings are in envelope conformations with the spiro C atoms at the flaps. The trifluoro­methyl-substituted benzene ring forms dihedral angles of 62.37 (14) and 87.40 (14)° with the benzene rings of the dihydro-1H-indene units. The two benzene rings form a dihedral angle of 36.94 (15)°. The mol­ecular structure is stabilized by intra­molecular C—H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol­ecules are linked into inversion dimers by pairs of inter­molecular C—H⋯O hydrogen bonds, generating R (2) (2)(10) ring motifs.
