Two-electron oxidation of a diiron complex (1) containing a bulky S-to-S bridge with an exocyclic carbonyl group affords 1(OH), which replicates the coordination structure and electronic configuration of H(air)(ox), and the chemically reversible reaction between 1 and 1(OH) mimics the bioprocess of interconversion of the inactive H(air)(ox) and the active Hred states of the [FeFe]-hydrogenases.
含有一个带有环外羰基的庞大硫-硫桥的二铁配合物（1）的双电子氧化产生[1(OH)]⁺，它复制了H(air)(ox)的配位结构和电子构型，并且1与[1(OH)]⁺之间的化学可逆反应模拟了[FeFe]-氢化酶的无活性H(air)(ox)和活性Hred状态相互转化的生物过程。
