Structure and synthesis

The trinuclear cluster is triangular with a double bond along one edge, which is also spanned by hydride ligands. It can be described as Os(CO)₄[Os(CO)₃(μ-H)]₂. This species is prepared by purging a solution of Os₃(CO)₁₂ with H₂ in octane (or other inert solvents of similar boiling point).^[1].

Os₃(CO)₁₂ + H₂ → Os₃H₂(CO)₁₀ + 2 CO

Reactions

The cluster reacts with a wide range of reagents under mild conditions. Illustrative is its reaction with [Ni(CO)(C₅H₅)]₂ to give Ni₃Os₃(CO)₉(C₅H₅)₃.
