Notes:
Azoalkane- und Nitrene-Bridged Carbonyl Metal Clusters of Iron and RutheniumBy using cluster buildup reactions, the new azoalkane-bridged clusters Ru3(CO)9(RN=NR) (3a, R=Me, 3b, R=Et), Fe2Ru(CO)9(EtN=NEt) (4), Ru4(CO)12(RN=NR) (5a, R=Me, 5b, R=Et), and FeRu3(CO)12(EtN=NEt) (6) were obtained. Upon attempts to prepare further such compounds, the N-N bond was cleaved resulting in nitrene-bridged clusters including the new compound Fe4(CO)11(μ4-NEt)2 (9). Cluster buildup starting from Ru3(CO)9(μ3-NPh)2 resulted in Ru4(CO)11(μ4-NPh)2 (10) and FeRu3(CO)11(μ4-NPh)2 (11). The crystal structures of 5b and 9 as well as some reactions of the nitrene-bridged clusters are described.
