A tungsten crown: The {SO4} units were introduced into the {W30} crown, resulting in a new Preyssler polyoxoanion {S5W30} 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).
