Biological and synthetic catalysts often utilize iron in high oxidation states (+IV and greater) to perform challenging molecular transformations. A coordination complex featuring an Fe(VII) ion has now been synthesized through sequential oxidations of nonheme iron–nitrido precursors.

把铁举得越来越高

生物和合成催化剂通常利用高氧化态（+IV 及更高）的铁来执行具有挑战性的分子转化。现在通过非血红素铁氮化物前体的连续氧化合成了一种以 Fe(VII) 离子为特征的配位络合物。
