Self-assembly of supramolecular boxes

Abstract

Supramolecular boxes are prepared from a dinucleating ligand and redox-active metal centres incorporated into the cavity framework without the need for ancillary ligands to block coordination sites on the metal; crystal structures of copper(I) and cadmium(II) cage structures of 4-thiomethyl-6-(3-pyridyl)-2,2′-bipyridine are reported.
