Nickel-Iron Dithiolato Hydrides Derived from H Activation by Their μ-Hydroxo Ligand-Containing Analogues.

Here, we describe the synthesis and characterization of the two μ-hydrido models of [NiFe]Hases prepared from a new type of H 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 KPF is also reported. Interestingly, the synthesis of the two μ-hydrido models from H activation represents the first functional modeling of the H activation catalyzed by the [NiFe]Hase (Ni-SIr) state to give the Ni-R state.
