A selective discussion on oxo-bridged diiron (III,III) centers in chemistry related to bio-functional activity

Diiron (III, III) oxo- bridged core is playing significant role in various biologically active compounds. Several synthetic diiron compounds are prepared which are the structural and functional models of these bio active centers. Extensive study over these compounds helps us to gain an idea about the mechanistic pathways adopted in the bio active centers. In vivo studies are highly expensive and critical. Analysis of these complexes outside the bio-environment is comparatively simple but give us an idea about the mechanistic overview of the metal centers which guide us for further proceedings.
