Abstract


This paper describes the synthesis and characterization of the non-symmetric ligands CH3SCH2CH2SRf (Rf = C6F5, C6HF4-4, C6H4F-2, C6H4F-3, C6H4F-4) as well as their platinum(II) derivatives cis-[PtCl2(CH3SCH2CH2SR f)] (Rf = C6F5, C6HF4-4, C6H4F-2, C6H4F-3, C6H4F-4) and trans-[PtCl2(CH3SCH2CH 2SRf)2] (Rf = C6F5, C6HF4-4). 19F NMR of these complexes show the presence of syn and anti isomers, consistent with a fast flipping of the metallacycle ring and a slow inversion of configuration at the dithioether sulfur atoms. The molecular and crystalline structures of the compounds cis-[PtCl2(CH3SCH2CH2SC 6F5)], cis-[PtCl2(CH3SCH2CH2SC 6H4F-3)] and trans-[PtCl2(CH3SCH2CH 2SC6F5)2], solved by X-ray diffraction are also described.
