Notes:
A series of mixed-metal carbonyl clusters containing Co and Ru atoms was investigated by 59Co NMR and, for the first time in cluster chemistry, by 99Ru NMR. These techniques were successfully used to follow the reactivity of these complexes towards nitrosylation by NO+. Whereas [NEt4] [RuCo3(CO)12] reacts with [NO]BF4 with the formation of RuCo3(CO)11(NO), which subsequently fragments into RuCo2(CO)11 and Co(CO)3(NO), [NEt4] [FeCo3(CO)12] leads inter alia to FeCo2(μ3-NH)(CO)9, in which the coordinated NO ligand has been reduced.
