“…[1] By allowing amines and aldehydes to condense around a metal template, a variety of metallosupramolecular structures, such as capsules [2] and interlocked assemblies, [3] have been synthesized, with applications including anion binding [4] and molecular magnetism. [5] This has been made possible through the use of metal-ion templates including octahedral Fe II , [6] Ni II , [7] Co II , [8] Zn II , [1h] and Cd II ions, [9] as well as tetrahedral Cu I [10] ions and higher-coordinate lanthanides.…”
