Diiron nonacarbonyl is an organometallic compound with the formula Fe₂(CO)₉. This metal carbonyl is a reagent in organometallic chemistry and of occasional use in organic synthesis. It is a more reactive source of Fe(0) than Fe(CO)₅. This micaceous orange solid is virtually insoluble in all common solvents.
