Redoxchemie, Zweikernkomplexe und Ru 3 ‐Clusterderivate des ”︁Liganden”︁ [Cp(Co) 2 Mn–CN] −

Redox Chemistry, Dinuclear Complexes, and Ru 3 ,‐Cluster Derivatives of the “Ligand” [Cp(CO) 2 Mn ‐ CN] − By means of the compounds Na[Cp(CO) 2 MnCN] ( 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) 2 Mn–CN–M] ‐ [form M = MnCp(CO) 2 and W(CO) 5 as PPN salts 2a, 3a ] as well as Cp(CO) 2 Mn–Cn–M [for M = MoCp(CO) 3 and NiCpPPh 3 , 4a, 5a ] were obtained in a pure state. From the reactions with Ru 3 (CO) 12 the cluster derivatives HRu 3 (CO) 10 [μ‐NC–Mn(CO) 2 Cp] ( 6a, b ) and Ru 3 (CO) 10 [μ‐NC–Mn(CO) 2 Cp] 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 .
