Abstract

original image

A new hexadentate ligand 1 was used to prepare the first FeIIFeIII complex that mimics the unsymmetrical coordination in the active site of one form of semimet hemerythrin. The different valences of the iron ions in this model complex are localized in solution, in analogy to the iron centers in the protein.
