Abstract

(Figure presented) Head over EELS: Reaction of O₂ with a hexa-iron(II)-substituted polyoxometalate in water yields a polyoxometalate with "end-on" hydroperoxo groups, {Fe^III-O₂H}, at the terminal positions. The hydroperoxo moiety, stabilized by hydrogen bonding with water, is unusual for its long O-O bond and nearly linear Fe-O-O bond angle. Electron energy-loss spectroscopy (EELS) is used to determine the oxidation state of iron.
