Swapping structures and cations : In an acid‐induced 3D‐to‐3D transformation at room temperature, K 6 Cd 4 Sn 3 Se 13 is converted into K 14− x H x Cd 15 Sn 12 Se 46 . The [Cd 15 Sn 12 Se 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.
