• The 3.5 nm-sized polyanion [H 4 Te IV 48 W VI 78 O 372 ] 80− , exhibiting an exceptionally high Te : W ratio, expands the structural role of Te IV ions from classical heterogroups within polyoxotungstate subunits to addenda ions. Investigations on the self-assembly conditions, proceeding in a simple one-pot reaction, point to the pH as one critical factor for circumventing this limitation. An unusually high tellurium content in [H 4 Te IV 48 W VI 78 O 372 ] 80− leads to Te centers assuming both the traditional heteroatom as well as the addenda functionalities.
