Four new mixed ligand iron(III) complexes of N,N′-dimethylethylenediamine based bis(phenol) di-amine (H2LNER) and 8-hydroxyquinoline (HQ) ligands have been synthesized and characterized by spectroscopic methods, X-ray diffraction, magnetic susceptibility measurements and cyclic voltammetry techniques. X-ray structure analysis revealed iron complexes with monoclinic or triclinic structures in which the H2LNEX and HQ ligands are coordinated to the Fe(III) center. The variable temperature magnetic susceptibility indicated a paramagnetic iron(III) center in the complexes. Electrochemical studies of the complexes with cyclic voltammetry showed cathodic peaks corresponding to an FeIII to FeII reduction. An anodic peak was found that corresponded to phenolate ligand oxidation to phenoxyl radicals in the positive potential regions. To the best of our knowledge, synthesis reports on mixed-ligand 8-hydroxyquinolinato iron(III) complexes are very rare.
