Abstract

original image

Silver in a gold mine: A triple-decker AuI–AgI ion cluster was synthesized by alternate alignment of cyclic trinuclear AuI complexes and AgI ions within a self-assembled cage. The box-shaped cavity of the cage is suitable not only for limiting the cluster number, but also for the stabilization of weakly associated metal ions, which cannot exist without the help of the cage.
