| Sumario: | This paper describes the synthesis and characterization ofthe platinum(II) compounds cis-[Pt(SCF3)2(RfSCH2CH2SRf)] Rf =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, showthe presence and interconvertion of syn and anti isomers, consistentwith a fast flipping of the metalocycle ring and a slow inversion ofconfiguration at the dithioether sulfur atoms. The molecular and crystallinestructures of the compounds [Pt(SCF3)2(2-C6H4FSCH2 CH2SC6H4F-2)] 3 and [Pt(SCF3)2(3-C6H4FSCH2CH2SC6H4F-3)] 4,solved by X-ray diffraction are also described. |
