Sumario:The 48‐Fe(III)‐containing 96‐tungsto‐16‐phosphate, [Fe(III) (48)(OH)(76)(H(2)O)(16)(HP(2)W(12)O(48))(8)](36−) (Fe(48)), has been synthesized and structurally characterized. This polyanion comprises eight equivalent {Fe(III) (6)P(2)W(12)} 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 {P(2)W(12)} POM precursor in water. The title polyanion was characterized by single‐crystal XRD, FTIR, TGA, magnetic and electrochemical studies.
