چکیده
In the title compound, C(29)H(20)F(3)NO(3)S, the thia-zolidine 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 trifluoro-methyl-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 mol-ecular structure is stabilized by intra-molecular C-H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol-ecules are linked into inversion dimers by pairs of inter-molecular C-H⋯O hydrogen bonds, generating R(2) (2)(10) ring motifs.
