(Butadiene)iron tricarbonyl is an organoiron compound with the formula (C4H6)Fe(CO)3. This coordination complex is a well-studied simple example of a (diene)iron tricarbonyl complex. An orange-colored viscous liquid that freezes just below room temperature, the compound adopts a piano stool structure.
== Synthesis and reactivity ==
The complex was first prepared by heating iron pentacarbonyl with the diene.
Protonation of the title complex with hydrogen chloride gives (allyl)Fe(CO)3Cl.
