Abstract: A complex host-guest equilibrium employing metal ions incorporated into both the host and guest is discussed. MIIX4 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 pentagonalprismatic Zn10L15 structure that incorporates both Br− and ClO4 − . Furthermore, the formation of heterometallic complexes provides direct evidence for metal exchange between the guest and host complex.
