(Butadiene)iron tricarbonyl explained

(Butadiene)iron tricarbonyl is an organoiron compound with the formula (CH)Fe(CO). It is a well-studied metal complex of butadiene.^[1] An orange-colored viscous liquid that freezes just below room temperature, the compound adopts a piano stool structure.^[2]

The complex was first prepared by heating iron pentacarbonyl with the diene.^[3]

Related compounds

Iron(0) complexes of conjugated dienes have been extensively studied. In the butadiene series, (η-CH)Fe(CO) and (η:η-CH)(Fe(CO)) have been crystallized.^[4] Many related complexes are known for substituted butadienes and related species. The species (η-isoprene)iron tricarbonyl is chiral.^[5]
