Abstract

On highly hydroxylated silica, Os₃(CO)₁₂, H₂Os₃(CO)₁₀ or Os₆(CO)₁₈ are simply physisorbed at room temperature. At 150°C there is an oxidative addition of the surface SiOH group to the OsOs bond of Os₃(CO)₁₂ with formation of the surface species: HOs₃(CO)₁₀(OSi). Such a structure was confirmed by the synthesis of the model compound HOs₃(CO)₁₀(OSi Ph₃). When the physisorbed clusters Os₃(CO)₁₂, H₂Os₃(CO)₁₀, Os₆(CO)₁₈ or the chemisorbed clusters HOs₃(CO)₁₀(OSi{A figure is presented}), are heated at 200°C, a breakdown of the cluster frame occurs, with formation of osmium(II) carbonyl species of the type [Os(CO)₂ (OSi{A figure is presented})₂]_n or [Os(CO)₃(OSi{A figure is presented})₂]₂. Similar reactions are observed on alumina.
