Abstract

The reactions between the palladium compounds [Pd₄(μ₃-CH)(μ-Cl)₃(PBu^t ₃)₄] or [Pd₂(μ-X)₂(PBu^t₃)₂] (X = Br or I) and [Co₂(CO)₈] have led to the novel palladium-cobalt tetranuclear compounds [CoPd₃(μ₃-X)(μ-CO)₃-(μ ₃-CO)(CO)(PBu^t₃)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 [Fe₂(CO)₉] and [Pd₂(μ-Br)₂(PBu^t₃)₂]} is also reported and has been structurally characterised as [Pd₆(μ-Br)₄(μ-CO)₄(PBu^t ₃)₄] (when X = Br). This hexanuclear cluster has triangular cluster moieties linked by double bromide bridges.
