Synthesis and molecular structure of trinuclear mixed-metal cluster cations containing arene and hydrido ligands

A series of mixed trinuclear arene ruthenium/osmium clusters is reported. The molecular structures of these mixed-metal cluster cations have been determined by single-crystal X-ray structure analysis of their salts. The single-crystal X-ray structure analyses of [1][BF4], [2][PF6] and [3][PF6] reveal an equiangular metal triangle despite the presence of an osmium atom in the metallic core.
