摘要：

This paper describes the synthesis and characterization of the non- symmetric ligands CH3SCH2CH2SRf(R-f = C6F5, C6HF4-4, C6H4F-2, C6H4F-3, C6H4F-4) as well as their platinum(II) derivatives cis-[PtCl2(CH3SCH2CH2SRf)] (R-f = C6F5, C6HF4-4, C6H4F-2, C6H4F-3, C6H4F-4) and trans-[PtCl2(CH3SCH2CH2SRf)(2)] (R-f = C6F5, C6HF4-4). F-19 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(CH3SCH2CH2SC6F5)], cis-[PtCl2(CH3SCH2CH2SC6H4F-3)] and trans[ PtCl2(CH3SCH2CH2SC6F5)(2)], solved by X-ray diffraction are also described.
