Reactions of Fe(CO)42- with metal carbonyl complexes lead to distinct mechanisms. Reaction with metal carbonyl cations gives a two-electron process that we interpret as a CO2+ transfer. Reaction with Mn2(CO)10 occurs by a single-electron transfer producing Fe2(CO)82- and Mn(CO)5-. Reaction with Mn(CO)5Br also occurs by a single-electron transfer. Reaction with Re(CO)5Br could be either SET or direct nucleophilic displacement. Kinetic studies are reported for several reactions.

A new mixed-metal ketenylidene complex, [PPN][MnCo2(CO)9(μ3-CCO)] (1) (PPN+ = bis(triphenylphosphine)nitrogen(1+)), has been prepared from trihalomethyl manganese complexes, Mn(CO)5(CX3) (X = Cl or Br), in combination with [PPN][Co(CO)4]. Attempts to extend this technique to other trihalomethyl complexes and metal carbonyl anions did not yield any new cluster products. Instead, these reactions were characterized by electron-transfer chemistry, which resulted in oxidation of the anions. Crystal data for 1: triclinic space group P1; a = 14.859 (4) A?, b = 9.209 (1) A?, c = 16.701 (3) A?, a = 90.08 (2)°, β = 102.79 (2)°, γ = 89.99 (2)° Z = 2. Protonation of 1 leads to the new mixed-metal methylidyne MnCo2(CO)10(μ3-CH) (2).
