Eine Puppe in der Puppe und noch eine drumherum - so erklärt Thomas Fässler seine Moleküle: Er packt ein Atom in einem Käfig in noch ein weiteres Atomgerüst. Mit ihrer großen Oberfläche könnten solche Strukturen als hocheffiziente Katalysatoren dienen. Wie bei dem russischen Holzspielzeug sitzt ganz innen drin ein einzelnes kleines Zinnatom, eingepackt in eine Hülle aus zwölf Kupferatomen, und diese ist nochmals umgeben von weiteren 20 Zinnatomen. In der Arbeitsgruppe von Professor Fässler am Institut für Anorganische Chemie der Technischen Universität München (TUM) gelangen solche aus drei Schalen aufgebauten räumlichen Strukturen als isolierte Metallcluster in Legierungen zum ersten Mal.
