Mutual stabilisation between M^II₄L₆ tetrahedra and M^IIX₄^2- metallate guests.

ABSTRACT: A complex host-guest equilibrium employing metal ions incorporated into both the host and guest is discussed. M^IIX₄^2- metallate guests are shown to provide a good size and shape match for encapsulation within the M₄L₆ tetrahedral capsules, facilitating the generation of previously unreported Zn₄L₆ complexes. Displacement of the initial, primary template anion (ZnBr₄^2-) by a secondary template anion (ClO₄^-) is shown to result in the formation of a pentagonal-prismatic Zn₁₀L₁₅ structure that incorporates both Br^- and ClO₄^-. Furthermore, the formation of heterometallic complexes provides direct evidence for metal exchan
