POM alert: The incorporation of an amide oxygen atom into the framework of the Dawson-type polyoxometalate (POM) cluster [P(2)V(3)W(15)O(62)](9-) (see picture) allows the communication of electronic effects between the organic and the inorganic parts of the molecule, including fine-tuning of the redox properties of the entire hybrid POM by the organic components, and transmission of the POM's electron-attracting properties to the organic moiety.
