Deskripsi
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 R22(10) ring motifs.
