Dodecanuclear Hexagonal-Prismatic M₁₂L₁₈ Coordination Cages by Subcomponent Self-assembly

Dodecanuclear hexagonal-prismatic M₁₂L₁₈ cages were prepared by a subcomponent self-assembly process with commercially available pyridinecarboxaldehyde, <i>m</i>-xylenediamine, and cadmium­(II) perchlorate or manganese­(II) perchlorate. The NMR spectrum of the Cd cage shows that there are three independent ligand sets, and the X-ray crystal structure of the Mn cage reveals that the structure has both <i>fac</i>-Δ- and <i>mer</i>-Λ-configured metal centers in a 1:1 ratio. The cage structure also has a large cavity that contains five perchlorate anions
