Azoalkane‐ und Nitrene‐Bridged Carbonyl Metal Clusters of Iron and Ruthenium By using cluster buildup reactions, the new azoalkane‐bridged clusters Ru 3 (CO) 9 (RNNR) ( 3a , RMe, 3b , REt), Fe 2 Ru(CO) 9 (EtNNEt) ( 4 ), Ru 4 (CO) 12 (RNNR) ( 5a , RMe, 5b , REt), and FeRu 3 (CO) 12 (EtNNEt) ( 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 Fe 4 (CO) 11 (μ 4 ‐NEt) 2 ( 9 ). Cluster buildup starting from Ru 3 (CO) 9 (μ 3 ‐NPh) 2 resulted in Ru 4 (CO) 11 (μ 4 ‐NPh) 2 ( 10 ) and FeRu 3 (CO) 11 (μ 4 ‐NPh) 2 ( 11 ). The crystal structures of 5b and 9 as well as some reactions of the nitrene‐bridged clusters are described.
