Abstract

A series of new palladium-ruthenium cluster complexes have been prepared by adding Pd(PBu^t₃) fragments to the ruthenium-ruthenium bonds of ruthenium carbonyl complexes. Reaction of Pd(PBu^t₃)₂ with Ru₃(CO)₁₂yielded the tripalladium adduct Ru₃(CO)₁₂[Pd(PBu^t₃)]₃ 1. Compound 1 contains three Pd(PBu^t₃) groups symmetrically disposed with each one acting as a bridge across one Ru-Ru bond of the former Ru₃(CO)₁₂ molecule. Reaction of Pd(PBu^t₃)₂ with Ru₆(CO)₁₇(C) yielded the dipalladium adduct Ru₆(CO)₁₇(C)[Pd(PBu^t₃)]₂ 2. Compound 2 exists as two isomers in the solid state. One isomer has Pd(PBu^t₃) groups bridging two edges of the Ru₆ octahedron. The other isomer has a Pd(PBu^t₃) group bridging one edge of the Ru₆ octahedron, and the other is a triple bridge. The reaction of Pd(PBu^t₃)₂ with Ru(CO)₅ yielded the dipalladium-diruthenium complex Ru₂(CO)₉[Pd(PBu^t₃)]₂ 3, a dipalladium adduct of the unstable molecule Ru₂(CO)₉.
