Vanadium-catechol coordination complexes have attracted significant interest due to their potential applications in catalysis, medicinal chemistry, and bioinorganic systems. In this study, we present the infrared absorption spectroscopic characterization of a series of vanadium catechol complexes, aiming to elucidate their coordination environment and bonding interactions. Fourier-transform infrared (FTIR) spectroscopy was used to investigate key vibrational modes of the complexes used to differentiate the structures, particularly the V=O stretching frequency. The changes in V=O stretching frequency of vanadium complexes bound to different catechol ligands will be discussed. The structures of vanadium complexes and comparisons of the solution and the solid-state structures will be presented. We will also determine if structural changes take place upon dissolution of the complexes in solution.
