Decacarbonyldihydridotriosmium is a chemical compound with the formula H2Os3(CO)10. This purple-violet crystalline air-stable cluster is notworthy because it is electronically unsaturated and hence adds a variety of substrates.
[edit] 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
[edit] 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.
