Abstract

The mixed-valent diiron(II, III) complexes of unsymmetrical phenolato ligand exchange are studied by Mossbauer spectroscopy and electrochemical techniques. The drastic effects of aqua ligand exchange and deprotonation on the electronic structure and redox potentials of diiron centers are illustrated.
