Polyoxometalates The reaction of early lanthanides, GeO 2 , and Na 2 WO 4 in buffered medium was systematically studied and a series of hexameric and dodecameric polyoxometalates with a closely related crown‐shaped framework based on [Ln 2 GeW 10 O 38 ] 6– Keggin‐type subunits was isolated. The dodecamers represent the first macroions with dual behavior in the formation of vesicle‐like structures that lead to different supramolecular assemblies in terms of composition and size by a solvent‐triggered skeletal modification of the species undergoing self‐association.
