Abstract

Two polyanions [Se^{I V}₂ Pd^II₄ W^VI₁₄ O₅₆ H]^11- and [Se^{I V}₄ Pd^II₄ W^VI₂₈ O₁₀₈ H₁₂ ]^12- are the first hybrid polyoxometalates in which classical (Group 5/6 metal based) and non-classical (late transition-metal based) polyoxometalate units are joined. Requiring no supporting groups, this co-condensation of polyoxotungstate and isopolyoxopalladate constituents also provides a logical link between POM-Pd^II coordination complexes and the young subclass of polyoxopalladates. Solid-state, solution, and gas-phase studies suggest interesting specific reactivities for these hybrids and point to several potential derivatives and functionalization strategies.
