This study reports on the metal nitrogen or metal oxygen stretching frequencies for the bonds between transition metal ions and quinoline derivatives. The quinoline derivatives are substituted with variable X groups coming off the 2 or 8 positions. The transition metals studied, including Co, Ni, and Cu, can be 4 or 6-coordinate and are known to form a bond with two or three bidentate quinoline derivative ligands. The nature of the metal ligand bonding will be characterized using Raman spectroscopy in solution and solid phases as well as their UV-Vis spectra to verify the formation of a complex.
