Resumo

The binuclear double-bridged acetylide complexes [Pt(μ-CCR)(C6F5)PPh3)]2 [R = Ph (1), But (2), SiMe3 (3)] have been synthesized from [trans-Pt(CCR)2(PPh3)2] and [cis-Pt(C6F5)2(THF)2] (THF = tetrahydrofuran). The crystal structure of [Pt(μ-CCPh) (C6F5)(PPh3)]2 (1) has been established by X-ray diffraction methods. The structure shows that two identical [(PPh3)(C6F5)PtCCPh] units are joined together through η2-bonding of MCCPh units. This indicates that the complex is formed via a rearrangement of groups between the two metal centres. Treatment of [Pt(μ-CCR)(C6F5)(PPh3)]2 with L (L = PPh3, py = pyridine) produces simple bridge-cleavage reactions giving the mono-nuclear complexes [trans-Pt(C6F5)(CCR)(PPh3)L] (4-9). © 1993.
