Heterometal Dopant Changes the Mechanism of Proton-Coupled Electron Transfer at the Polyoxovanadate-Alkoxide Surface.

ABSTRACT: The transfer of two H-atom equivalents to the titanium-doped polyoxovanadate-alkoxide, [TiV₅O₆(OCH₃)₁₃], results in the formation of a V(III)-OH₂ site at the surface of the assembly. Incorporation of the group (IV) metal ion results in a weakening of the O-H bonds of [TiV₅O₅(OH₂)(OCH₃)₁₃] in comparison to its homometallic congener, [V₆O₆(OH₂)(OCH₃)₁₂], resembling more closely the thermodynamics reported for the one-electron reduced derivative, [V₆O₆(OH₂)(OCH₃)₁₂]^1-. An analysis of early time points of the reaction of [TiV₅O₆(OCH₃)
