Abstract

Cores and effect: Heating the cluster [W18O56(SO3)2(H2O)2]8− causes an electron transfer from the core sulfite anions to the cluster shell resulting in a color change from colorless to dark blue (see backgrounds). The electron transfer is coupled with a structural reorganization of the cluster shell and oxidation of the sulfite to sulfate anions (see scheme).
