The complex [FeIII2(μ-O2)(L3)4(S)2]4+ (L3 = 2-(4-thiazolyl)benzimidazole, S = solvent) forms upon reaction of [FeII(L3)2] with H2O2 and is a functional model of peroxo-diiron intermediates invoked during the catalytic cycle of oxidoreductases. The spectroscopic properties of the complex are in line with those of complexes formed with N-donor ligands. [FeIII2(μ-O2)(L3)4(S)2]4+ shows both nucleophilic (aldehydes) and electrophilic (phenol, N,N-dimethylanilines) oxidative reactivity and unusually also electron transfer oxidation.
配合物[FeIII2(μ - O2)(L3)4(S)2]4+（L3 = 2 - (4 - 噻唑基)苯并咪唑，S = 溶剂）由[FeII(L3)2]与H2O2反应形成，是氧化还原酶催化循环中涉及的过氧 - 二铁中间体的功能模型。该配合物的光谱性质与由氮供体配体形成的配合物的光谱性质一致。[FeIII2(μ - O2)(L3)4(S)2]4+既表现出亲核（醛）和亲电（苯酚、N,N - 二甲基苯胺）氧化反应性，而且还表现出异常的电子转移氧化反应性。
