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.
