摘要：

The reactions between the palladium compounds [Pd-4(mu(3)-CH)(mu-Cl)(3)(PBu3t)(4)] or [Pd-2(mu-X)(2)(PBu3t)(2)] (X = Br or I) and [Co-2(CO)(8)] have led to the novel palladium-cobalt tetranuclear compounds [CoPd3(mu(3)-X)(mu-CO)(3)(mu(3)-Co)(CO)(PBu3t)(3)] (X = Cl, Br or I). Structural characterisation of one of them (X = Cl) has shown that the metal cluster geometry is intermediate between a tetrahedron and a butterfly. A Second product detected in this reaction {and additionally with [Fe-2(CO)(9)] and [Pd-2(mu-Br)(2)(PBu3t)(2)]} is also reported and has been structurally characterised as [Pd-6(mu-Br)(4)(mu-CO)(4)(PBu3t)(4)] (when X = Br). This hexanuclear cluster has triangular cluster moieties linked by double bromide bridges.
