CERVANTES, Ruy; DURAN, Ubaldo; BERNES, Sylvain  and  TORRENS, Hugo. CF₃S-Platinum(II) Complexes with Fluorinated Dithioethers: Molecular Structures of [Pt(SCF₃)₂(R_fSCH₂CH₂SR_f)] R_f = C₆H₄F-2 and C₆H₄F-3. J. Mex. Chem. Soc [online]. 2007, vol.51, n.1, pp.20-26. ISSN 1870-249X.

This paper describes the synthesis and characterization of the platinum(II) compounds cis-[Pt(SCF₃)₂(R_fSCH₂CH₂SR_f)] R_f = C₆F₅ 1, C₆HF₄-4 2, C₆H₄F-2 3, C₆H₄F-3 4, C₆H₄F-4 5 and C₆H₄(CF₃)-3 6. Variable temperature ¹⁹F NMR spectra of these complexes, show the presence and interconvertion of syn and anti isomers, consistent with a fast flipping of the metalocycle ring and a slow inversion of configuration at the dithioether sulfur atoms. The molecular and crystalline structures of the compounds [Pt(SCF₃)₂(2-C₆H₄FSCH₂CH₂SC₆H₄F-2)] 3 and [Pt(SCF₃)₂(3-C₆H₄FSCH₂CH₂SC₆H₄F-3)] 4, solved by X-ray diffraction are also described.

Keywords : fluorothiols; fluorothioetheres; platinum; VT-NMR; X-ray.
