Inorganic crown ethers: sulfate-based Preyssler polyoxometalates.
A tungsten crown: The {SO(4)} units were introduced into the {W(30)} crown, resulting in a new Preyssler polyoxoanion {S(5)W(30)} with position-specific, guest, K(+) or Na(+) ions in its geometrical center. The as-prepared polyoxoanion exhibits an interesting ion-selective encapsulation of K(+) and Na(+) (see figure).
