Supramolecular self-assembly of finite and infinite frameworks through coordination

This article discloses self-assembling finite and infinite coordination compounds with unique structures and properties. Macrocycles, catenanes, and cages self-assemble quantitatively from a cis-protected Pd(II) complex and appropriate pyridine-based bridging ligands. These discrete structures are expanded to infinite frameworks when the same ligands are complexed with a non-protected Cd(ll) ion.
