Abstract

The reaction of molecular hydrogen with HOs₃(CO)₁₀(NO) leading to the reduction of the nitrosyl ligand has been studied. Four products have been isolated and a reasonable mass balance of osmium has been obtained. Two of the products, H₂Os3(NH)(CO)₉ and the unusual hydrogen-rich cluster H₄Os₃(NH)(CO)₈ are new, and spectroscopic data for their formulations and proposed structures are presented. The other two products, HOs₃(NH₂)(CO)₁₀ and H₄Os₄(CO)₁₂, have been previously characterized. A new route to HOs₃(NH₂)(CO)₁₀ starting from the triazenido cluster, HOs₃(HN₃H)(CO)₁₀, has also been studied. Interconversions between the imido and amido clusters were investigated.
