摘要：

A series of mixed-metal carbonyl clusters containing Co and Ru atoms was investigated by Co-59 NMR and, for the first time in cluster chemistry, by Ru-99 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(mu-3-NH)(CO)9, in which the coordinated NO ligand has been reduced.
