Diiron amido-imido complex [(Cp*Fe)2(μ2- NHPh)(μ2-NPh)]: Synthesis and a net hydrogen atom abstraction reaction to form a bis(imido) complex

A reaction between [Cp*FeCl]_x and LiNHPh (1 equiv to Fe) produces a new paramagnetic Fe(II)-Fe(III) μ₂-amido- μ₂-imido complex [(Cp*Fe)₂(μ₂-NHPh) (μ₂-NPh)] (1), which, upon interaction with 2,2′-azobis(2,4- dimethylvaleronitrile), undergoes a net N-H hydrogen atom abstraction reaction to give a diamagnetic Fe(III)-Fe(III) μ₂-imido dimer [Cp*Fe(μ₂-NPh)]₂ (2). The molecular structures of 1 and 2 have been determined by single-crystal X-ray diffraction.
