But the electrochemical results show that complexes exhibitcompletely irreversible redox behaviour which is different from thatfound in diiron proteins. 1.3 To obtain the diiron species which are stable to elec-trochemical reduction, a series of new tetranuclear cage ironspecies containing two 〓 cores, with using hexadentatepolybenzimidazole ligands, were synthesized and characterized by vari-ous spectroscopic methods. Their physical properties have been investi-gated. The crystal structures of 〓〓tetrakis (benzimidazol-2-ylmethyl)-1, 4-diaminobutane and 〓,〓-tetrakis ( N-ethylbenzimidazol-2-ylmethyl )-1, 4-diaminobutane were determined. They contain two 〓 cores which arelinked to each other by -〓-chain in the ligands.
