Tris-decorated multi-iron polyoxotungstates

Abstract

Solution-stable tris(hydroxymethyl)aminomethane-functionalized Fe^III-containing polyoxotungstates exhibit an unusual anchoring mode of triol moieties, with one –NH₂ and one –CH₂OH group remaining accessible for post-functionalization or chemisorption. The redox-active title compounds have been isolated under unusually mild reaction conditions and characterized in the solid state and in aqueous solutions.
