The reactions of Ru3(CO)11L, HRu3(CO)8(C2Bu^t)L (L=DPPA, CH3CN) with (η⁵-C5H5)NiM3(μ-H)3(CO)8L (M=Ru, Os; L=DPPA, CH3CN) lead to cluster interlinked derivatives, with DPPA acting as a bridge (DPPA=bis(diphenylphosphino)acetylene).The complexes have been identified by elemental analyses and spectroscopy.Side reactions, such as displacement of ligands or thermal disproportionation, have been observed.
