摘要：

The reaction between [Fe-2(CO)(9)] and [Cp(CO)(2)MnPt(mu-C=CHPh)(dppp)] (1), where dppp is Ph(2)P(CH2)(3)PPh(2), proceeds stepwise, initially through transmetalation of the bridging vinylidene ligand, i.e. with replacement of the [Mn(CO)(2)Cp] fragment by the [Fe(CO)(4)] group, to produce the novel binuclear mu-vinylidene complex [(dppp)PtFe(mu-C=CHPh)(CO)(4)] (2), which reacts further with [Fe-2(CO)(9)] to yield the tetranuclear cluster [(dppp)PtFe3(mu(4)-C=CHPh)(CO)(9)] (3) and the trinuclear complex [(dppp)PtFe2(CO)(8)] (4). The IR and H-1, C-13 and P-31 NMR data for the new complexes are reported and discussed.
