Resum

The mixed early-late Ti-Pt2 compound [(η5-C5H4SiMe3) Ti(μ3-1η5-C5H4P(S) Ph2-2,3κS)(μ-SPh)2{Pt(C6 F5)2}2] (3) containing a functionalised thiophosphorylcyclopentadienyl S=PPh2C5H4 bridging ligand has been obtained by reaction of [(η5-C5H4SiMe3) (η5-C5H4P(S)Ph2) Ti(SPh)2] (1) with 2 equivalents of cis-[Pt(C6F5)2(thf)2]. The crystallisation of 3 in CH2Cl2/MeOH at -20°C gave the unexpected diplatinum complex [Pt(C6F5)2(μ-SPPh2 C5H5)]2 (4) with an unusual double bis-cyclopentadienyldiphosphine sulphide bridging system (μ-κS), which has been characterised by X-ray diffraction. As an alternative route to the synthesis of 4 the reaction of cis-[Pt(C6F5)2(thf)2] with S=PPh2C5H5 has been studied. Independently of the stoichiometry employed, this reaction gives mixtures of 4 and the novel mononuclear complex cis-[Pt(C6F5)2(S=PPh2 C5H5)2] (6). Low temperature control of this reaction indicates that both complexes (4 and 6) are formed through a common intermediate identified as cis-[Pt(C6F5)2(S=PPh2 C5H5)(thf)] (5) on the basis of spectroscopic techniques. © 2001 Elsevier Science B.V.
