| Summary: | In the title compound, C29H20F3NO3S, 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.
