TEMPLATE-CONTROLLED FORMATION OF CLUSTER SHELLS OR A TYPE OF MOLECULAR RECOGNITION - SYNTHESIS OF [HV22O54(CLO4)]6- AND [H2V18O44(N3)]5-

Anions as templates for “host” anions determine the shape of molecular cavities (cluster shells) which form from differently coupled tetragonal‐pyramidal OVO4 building blocks. For example, in the case of the cluster anions [HV22O54(ClO4)]6− and [H2V18O44(N3)]5− (depicted on the right) the construction of the cluster shells are achieved by “recognition” of the (OO)2− or N(N)N units.
