Recent developments in the metallo-supramolecular chemistry of oligo-β-diketonato ligands

Abstract Classical β-diketone ligands have been well demonstrated to exhibit a rich metal coordination chemistry yielding metal complexes displaying a variety of properties. The investigation of polydentate ligand derivatives containing more than one β-diketone domain, and in many instances also incorporating additional donor sites, have been demonstrated to react with a range of metal ion types to yield a wide range of metallo-supramolecular topologies. These include metallocyclic platforms, triangles, squares, cubes, helicates, tetrahedrons as well as other intricate structures that include a universal 3-ravel. In this report we cover the published literature in the area from 2008 with emphasis on the synthetic strategies employed as well as on the diverse structures of the metallo-supramolecular products obtained.
