Abstract

Redox Chemistry, Dinuclear Complexes, and Ru3,-Cluster Derivatives of the “Ligand” [Cp(CO)2Mn - CN]− By means of the compounds Na[Cp(CO)2MnCN] (1a, b) the abilities of the cyanide ion to link different organometallic units and to stabilize unusual electron counts in organometallic complexes were tested. The dinuclear complexes [Cp(CO)2Mn–CN–M]- [form M = MnCp(CO)2 and W(CO)5 as PPN salts 2a, 3a] as well as Cp(CO)2Mn–Cn–M [for M = MoCp(CO)3 and NiCpPPh3, 4a, 5a] were obtained in a pure state. From the reactions with Ru3(CO)12 the cluster derivatives HRu3(CO)10[μ-NC–Mn(CO)2Cp] (6a, b) and Ru3(CO)10[μ-NC–Mn(CO)2Cp]2 (7b) were characterized. One-electron transfers were investigated for the starting complex and for the two anionic dinuclear complexes 2a, 3a. Crystal structures were determined of the dinuclear Mn–CN–Mn compex 2a and of the two cluster derivatives 2b, 7b.
