摘要：

The 48-Fe-III-containing 96-tungsto-16-phosphate, [Fe-48(III)(OH)(76)(H2O)(16)(HP2W12O48)(8)](36-) (Fe-48), has been synthesized and structurally characterized. This polyanion comprises eight equivalent {(Fe6P2W12)-P-III} units that are linked in an end-on fashion forming a macrocyclic assembly that contains more iron centers than any other polyoxometalate (POM) known to date. The novel Fe-48 was synthesized by a simple one-pot reaction of an {Fe-22} coordination complex with the hexalacunary {P2W12} POM precursor in water. The title polyanion was characterized by single-crystal XRD, FTIR, TGA, magnetic and electrochemical studies.
