Graphical Abstract

Big W: One of the largest polytungstates, the 20 cerium(III) atom tungstogermanate [Ce20Ge10W100O376(OH)4(H2O)30]56− (1), has been synthesized from CeIII ions and [α-GeW9O34]10− in aqueous acidic medium at pH 5.0. Polyanion 1 represents the first lanthanide-substituted tungstogermanate and can be described as a dimer that is linked through long CeO(W) bridges.
