Abstract

The study and understanding of the coordination behavior of functional ligands with d¹⁰ "closed shell" metals has been active for many years, as it will continue to expand along with advances in characterization techniques such as X-ray crystallography. Interactions present in these metal complexes are typically associated with hydrogenbonding, π-π stacking effects, electrostatic and van der Waals interactions, of which none could be observed without an X-ray examination of the structure. As a result, design and synthesis of discrete and multi-dimensional coordinative structures have been made possible by understanding the binding behavior of the ligand and the different factors (anion, solvent, temperature, metal/ligand ratio) involved in the formation of the organic coordination architectures. In this work several multidentate pyridyl-phosphine ligands and their corresponding oxides have been used to construct a family of novel compounds, and bipyridine type molecules to synthesize mixed ligand complexes that vary from discrete molecules to polymeric arrays depending on the binding sites of the bipyridine. The luminescence, UV-visible, and electrochemical properties of these complexes were also studied, and seen to be dependent on the changes in structure and metal environment.
