Abstract

Two new mixed-metal sandwich complexes [MII2(H2O)2FeIII2(P2W15O56)2]14− (abbreviated {M2Fe2P4W30}, MII = CoII, MnII) were obtained at pH 3 by addition of M2+ to [Na2(H2O)2FeIII2(P2W15O56)2]16− (abbreviated {Na2Fe2P4W30}) without substitution in the α-[P2W15O56]12− (abbreviated {P2W15}) units. Their X-ray structures are reported. At lower pH, back conversion to {Na2Fe2P4W30} was followed by 31P NMR, electrochemistry and UV-visible spectroscopy. The preparation and the characterization in solution of the lacunary intermediate [NaCoII(H2O)2FeIII2(P2W15O56)2]15− (abbreviated {NaCoFe2P4W30}) is also described.
