The rate and activation parameters for the cleavage of the metal-metal bond of the anion radical of a di-iron carbonyl complex
Davies SG., Simpson SJ., Parker VD.
Electron transfer to [(C5H5)Fe(CO)2]2gives an anion radical in which the electronic configuration of one Fe no longer conforms to the '18 e' rule and which undergoes cleavage of the metal-metal bond with a rate constant equal to 1060 s-1at 273 K and an activation energy of 15.7 kcal mol-1(1 kcal = 4.18 kJ) in acetonitrile.
