The new 17-electron species [Fe(eta(4)-P2C2tBu2)2]- (2) and 16-electron species [Fe(eta(4)-P2C2tBu2)2] (3) are rare examples of readily accessible, open-shell iron sandwich complexes with phosphaorganic ligands. The presented data lead us to conclude that phosphorus derivative (3) is a true analogue of the elusive bis(eta(4)-cyclobutadiene)iron(0) compound (1). Currently, we are investigating whether (1) and its derivatives are likewise accessible. Future studies will focus on a more detailed characterization of the iron oxidation state in (1)-(3) and the influence of metal coordination on the magnetic and redox properties of these compounds.
