Chemistry of the metal carbonyls. Part LV. Synthesis of polynuclear carbonyl(iron–ruthenium) complexes

Abstract

Reactions between pentacarbonyliron and dimeric tricarbonyl(dichloro)ruthenium or dodecacarbonyltriruthenium under a variety of conditions afford the new polynuclear metal carbonyl cluster compounds Fe₂Ru(CO)₁₂, FeRu₂(CO)₁₂, and H₂FeRu₃(CO)₁₃, as well as the previously reported H₂Ru₄(CO)₁₃. Similarly, reaction between octacarbonyldicobalt and [Ru(CO)₃Cl₂]₂ gives the compound HRuCo₃(CO)₁₂. Some properties of the compounds are discussed in relation to those of other species of formula M₃(CO)₁₂ and H₂M₄(CO)₁₃(M = Fe, Ru, or Os).
