Abstract

We have used Raman and IR spectroscopy to study the oxidation reaction of sulfitegroups in the unique polyoxometalate compound K7Na[WVI18O56(SO3)2(H2O)2]·20H2O with a structure related to the Wells–Dawson type in situ at high temperature and high pressure. The results give new insights into the unusual redox process that occurs in this compound with electrons and O2− ions transferred between the polyoxometalate cluster and SO32−/SO42−groups held within the cage in a process that has been termed the “Trojan Horse” effect.
