Synthesis, structural, magnetic, and redox properties of asymmetric diiron complexes with a single terminally bound phenolate ligand. Relevance to the purple acid phosphatase enzymes

An electrochemical analysis of the synthesis and the structural, redox and magnetic characteristics of asymmetric diiron complexes mimicking the binding of a single terminal tyrosinate was conducted. Findings showed that the introduction of the single terminal phenolate had a drastic influence on the redox properties of the complexes resulting in the thermodynamic destabilization of the diferrous state which was higher than the stabilization of the diferric state.
