Abstract

Encapsulated in a protective [{Fe(pz)3}4] outer layer, which provides the complex with structural stability, the octanuclear complex [Fe8(μ4-O)4(μ-pz)12Cl4] contains a Fe4O4 core (see drawing) that withstands four consecutive reversible one-electron reductions. Iron–oxygen clusters are shown to possess redox properties which rival those of their better studied iron–sulfur analogues. pz=pyrazolate anion.
