Abstract

original image

Goldener Käfig: Die beiden kleinsten anionischen Gold-Käfige, Au16 und Au17, wurden mit Kupferatomen unter Bildung der Clusteranionen CuAu16 (siehe Bild) bzw. CuAu17 dotiert. Deren Photoelektronenspektren lassen darauf schließen, dass die Strukturen der ursprünglichen Käfige durch die Dotierung praktisch nicht verändert werden. Nach Berechnungen ist das Cu-Atom, ähnlich wie bei endohedralen Fullerenen, im Zentrum des Käfigs lokalisiert.
