Old Clusters with New Tricks: Engineering S…S Interactions and Novel Physical Properties in Sulfite-Based Dawson Clusters

摘要

Polyoxometalates (POMs) have been subjected to a vast number of studies due to attractive electronic and molecular properties that give rise to a variety of applications, for example, in catalysis, medicine, and materials science. A notable subset of POM-based clusters are those of the very stable Dawson structural type [M_(18)O_(54)(XO_4)_2]~(m-) (M = Mo,W; X = main-group element), first discovered fifty years ago and since then the subject of many hundreds of papers.
