Earth abundant metal complexes are desirable due to their reduced cost and lower toxicity. Iron complexes coordinated by two (bis), phenylene bridged CCC-NHC pincer ligands have been synthesized via metalation/transmetalation methodology and were characterized by <sup>1</sup>H NMR, cyclic voltammetry, UV-Vis spectroscopy, X-ray diffraction, mass spectrometry and computational studies. The bis (CCC-NHC) iron complexes exhibits a mild Fe(III)/Fe(IV) oxidation potential. Therefore, attempts to achieve higher, historically less accessible, oxidation states have been performed. Additionally, these complexes have had ligand functionalization performed post-transmetalation to fine tune the redox potentials of these complexes. The latest results will be presented.
