Coupled reaction equilibria enable the light-driven formation of metal-functionalized molecular vanadium oxides.

ABSTRACT: The introduction of metal sites into molecular metal oxides, so-called polyoxometalates, is key for tuning their structure and reactivity. The complex mechanisms which govern metal-functionalization of polyoxometalates are still poorly understood. Here, we report a coupled set of light-dependent and light-independent reaction equilibria controlling the mono- and di-metal-functionalization of a prototype molecular vanadium oxide cluster. Comprehensive mechanistic analyses show that coordination of a Mg²⁺ ion to the species {(NMe₂H₂)₂[V^V₁₂O₃₂Cl]}^3- results in formation of the mono-functionalized {(NMe₂H₂)[(MgCl)V^V₁₂O₃₂Cl]}^3- with simultaneo
