Abstract

Swapping structures and cations: In an acid-induced 3D-to-3D transformation at room temperature, K₆Cd₄Sn₃Se₁₃ is converted into K_14-xH_xCd₁₅Sn 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. (Figure Presented)
