Encapsulated in a protective [{Fe(pz) 3 } 4 ] outer layer, which provides the complex with structural stability, the octanuclear complex [Fe 8 ( μ 4 ‐O) 4 ( μ ‐pz) 12 Cl 4 ] contains a Fe 4 O 4 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.
