The ability to tune the electronic properties of coordination complexes is greatly enhanced by the large diversity of mono-, bi-and tri-dentate phosphines derivatives. These commercially available ligands may have a variety of aryl and alkyl substituents, variable bridge lengths and well-defined cone angles. The synthesis of coordination complexes with different phosphine ligands allows a systematic study of the structureproperty relationships and the effect of the ligand on other material properties such as non-linear optical and catalytic effects. These compounds have increased electron density from the large aromatic systems that branch off of the phosphorous atoms, while the whole coordination complex has increased stability due to the chelating effect.
