Metallo-supramolecular assemblies incorporating 1,3-and 1,4-aryl linked bis-beta-diketones - Some recent studies

Abstract

A review of recent work in the authors' laboratories involving the interaction of 1,3- and 1,4-aryl linked bis-β-diketone derivatives with divalent and trivalent metal ions is presented. In some instances, bifunctional bridging ligands have been employed to extend the resulting structures from two to three dimensions. Examples of metallo-supramolecular dinuclear 'platforms', tetranuclear cofacial dimers, dinuclear helicates, trinuclear triangles, stepped metallo-polymers, a prismatic columnar polymer and large cavity-containing, tetranuclear tetrahedra are all discussed
