Graphical Abstract

Eine Klasse von Uranylperoxid-Clustern wurde früher als nanometergroße Ionen, die sich spontan in wässriger Lösung bilden, entdeckt. Der untersuchte Uranyl(VI)-Cluster hat einen Durchmesser von 2 nm und enthält 24 Uranyl- und 12 Phosphor-Einheiten. NMR-Spektroskopie zeigte, dass das Ion zwei Formen hat, die sich innerhalb von Millisekunden bis Sekunden ineinander umwandeln, abhängig von Temperatur und Größe der Gegenionen. P blau, O rot, U gelb.
