| Abstract: | In search of organometallic Prussian Blue analogs with cluster constituents the cyanoiron complexes Cp(CO)2Fe-CN and Cp(dppe)Fe-CN were used as ligands to replace CO in the clusters Fe3(CO)12, Ru3(CO)12, RuCo,(CO)11, Co4(CO)12, Fe3(CO)9(µ3-P1Bu)2, Fe3(CO)9(µ3-PPh)2, and Co3(CO)9 (µ3-CMe). 11 new complexes of the type LnFe-CN-Cluster were obtained. Their constitution was ascertained crystallographically for Cp(CO)2Fe-CN-RU3(CO)11 and Cp(CO)2Fe-CN-RuCo2(CO)10 showing that unlike phosphine ligands the cyanoiron ligands occupy axial positions on the cluster. Cyclic voltammetry has shown that unlike the parent clusters these derivatives are more easily oxidized than reduced. |
