Dicarbonyl(⁵-1-carboxycyclopentadienyl)methyliron(II)

Abstract: The title carboxyl-functionalized iron complex, [Fe(CH₃)(C₆H₅O₂)(CO)₂], was prepared by the reaction of CO₂ with a lithiated parent unsubstituted compound. The Fe(CO)₂Me legs of the tripodal piano stool are characterized by disorder between the methyl group and the carbonyl group, and the two ligands were refined (50% site occupancy) over the two positions. The ligands are alternately located on either side of a local pseudo-mirror plane running through the carboxylic functionality and the central Fe atom.
