Abstract

The photochemistry of Fe(CO)₅ adsorbed on Si0₂ at submonolayer coverage has been studied. IR and UV-visible spectra show that the only significant product is Fe₃(C0)₁₂ rather than Fe₂(C0)₉, which is the product observed upon irradiation of Fe(C0)₅ in the gas or liquid phase or in solution. Evidence is presented that the intermediate reacting to give Fe₃(CO)₁₂ on the Si0₂ surface is a species designated Fe(C0)₄(Si0₂), which denotes a complex between Fe(C0)₄ and the terminal surface hydroxyl groups or siloxane bridging oxo groups.
