Redox-inactive ions control the redox-activity of molecular vanadium oxides.

ABSTRACT: Polyoxometalates are key materials for energy conversion and storage due to their unique chemical tunability and electrochemical reactivity. Herein, we report that functionalization of molecular vanadium oxides, polyoxovanadates, with redox-inert Ca²⁺ cations leads to a significant increase in their electron storage capabilities. The electrochemical performance of the Ca²⁺-functionalized dodecavanadate [Ca₂V₁₂O₃₂Cl(DMF)₃]^2- (={Ca ₂ V ₁₂ }) was thus compared with that of the precursor compound (H₂NMe₂)₂[V₁₂O₃₂Cl]^3- (={V ₁₂ }). {Ca ₂ V<
