Chiral hole : The first chiral microporous germanium antimony sulfide with 3D helical channels was constructed by the unprecedented combination of {GeS 4 } tetrahedra and ψ‐{SbS 4 } trigonal bipyramids. The dimethylammonium cations present in the structure are easily exchanged with alkali metal cations present in aqueous solution. The title compound has high ion‐exchange capacity and high selectivity for Cs + ions.
