Template‐Controlled Formation of Cluster Shells or a Type of Molecular Recognition: Synthesis of [HV₂₂O₅₄(ClO₄)]⁶⁻ and [H₂V₁₈O₄₄(N₃)]⁵⁻

Abstract

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.
