Abstract
A series of mixed‐metal carbonyl clusters containing Co and Ru atoms was investigated by ^59^Co NMR and, for the first time in cluster chemistry, by ^99^Ru NMR. These techniques were successfully used to follow the reactivity of these complexes towards nitrosylation by NO^+^. Whereas [NEt~4~] [RuCo~3~(CO)~12~] reacts with [NO]BF~4~ with the formation of RuCo~3~(CO)~11~(NO), which subsequently fragments into RuCo~2~(CO)~11~ and Co(CO)~3~(NO), [NEt~4~] [FeCo~3~(CO)~12~] leads inter alia to FeCo~2~(μ~3~‐NH)(CO)~9~, in which the coordinated NO ligand has been reduced.
