Abstract

Swapping structures and cations: In an acid-induced 3D-to-3D transformation at room temperature, K6Cd4Sn3Se13 is converted into K14-xHxCd15Sn 12Se46. The [Cd15Sn12Se 46]14- framework, which contains a tunnel network of accessible cages of labyrinthine complexity (see picture), is highly robust, acid resistant, and has excellent ion-exchange properties.
