Bridging the gap between solution and solid state studies in polyoxometalate chemistry: Discovery of a family of [V_1 M_(17)]-based cages encapsulating two {V~v O_4} moieties

摘要

A family of polyoxometalates with the composition [H_2V_3M_(17)O_(62)]~(6-) features a Dawson-like architecture containing two tetrahedral {V~vO_4} templates rather than main group hetero-anions ({PO_4} or {SO_4} etc.) typically associated with classical heteropolyacids, situated within a mixed-metal {M~(VI)_(17)V~(IV)O_(54)} cage and these clusters were first discovered using mass spectrometry.
