geometries. To confirm this, crystal structure determinations were carried out for both 2 and 3. Spectroscopic and structural evidence for both 2 and 3 suggests a new class of metal clusters consisting of an orthometallated trinuclear carbonyl cluster unit rigidly linked to a ferrocenyl moiety through an aromatic pathway. Electrochemical investigations revealed that both 2 and 3 undergo a reversible one-electron
