Copper complexes with various phenanthroline ligands have been studied extensively over the past century. Initial studies in our research group began with mono- and bis-phenanthroline complexes of copper, and these studies have recently been expanded to include the tris-phenanthroline copper complexes. In each case, a series of complexes has been studied using ligands with various electron donating or electron withdrawing substituents in the 5 and/or 6 positions of the phenanthroline In the current project, a consistent method for synthesizing the desired 3:1 products has been established. The compounds have been characterized by using electronic spectroscopy, cyclic voltammetry, FTIR, and X-ray crystallography.
