Abstract

Here, we describe the synthesis and characterization of the two μ-hydrido models of [NiFe]H₂ases prepared from a new type of H₂ activation by the corresponding two μ-hydroxo models. In addition, another μ-hydrido model prepared by the anionic exchange between one of the two μ-hydrido models and KPF₆ is also reported. Interestingly, the synthesis of the two μ-hydrido models from H₂ activation represents the first functional modeling of the H₂ activation catalyzed by the [NiFe]H₂ase (Ni-SIr)_I state to give the Ni-R state.
