The interaction of [VIVO(acac)2], acac = acetylacetonato, with H-chain ferritin has been studied. After dissociation and partial oxidation, [VIVO(acac)2] forms a mixed-valence [V15O36(Cl)]6− ion, which non-covalently binds with the protein nanocage. This polyoxidovanadate is formed at alkaline pH, showing that proteins can favor the formation and stabilization of species hardly isolable in solution.
