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).
