Electrochem. and absorption spectroscopy (UV/Vis, IR) of the complex 1·[BF4]4 reveal only a small degree of metal-to-ligand \textgreek{p} back donation, in contrast to previously characterized compds. [(TCNE)(MLn)4]. Accordingly, the one-electron reduced [(\textgreek{m}4-TCNE)[CpFe(CO)2]4]3+ exhibits a very well resolved EPR spectrum at g = 1.9965 with detectable coupling of 0.055 mT for 57Fe in natural abundance from four coordinated [Fe(CO)2(C5H5)]+ groups.
