We have been studying the formation of polynuclear host complexes by reaction of multifunctional β-diketones with metals such as Cu2+.  Bis(β-diketones) such as m-pbaH2 (see figure) yield molecular squares of ca. 1.4 nm diameter, which bind guests such as 4,4′-bpy and C60.  Trifunctional ligands can lead to metal-organic polyhedra (MOPs), including dodecahedra M30L20 (ca. 5 nm diameter).  Geometric distortions in coordinated β-diketonates, and the optimum selection of ligands for construction of supramolecular complexes, will also be discussed.
