Journal of the American Chemical Society, 2011•ACS PublicationsHydrogenation and protonation of parent imido complexes have attracted much attention in
relation to industrial and biological nitrogen fixation. The present study reports the structure
and properties of the highly unsaturated diiridium parent imido complex [(Cp* Ir) 2 (μ2-H)(μ2-
NH)]+ derived from deprotonation of a parent amido complex. Because of the Lewis acid–
Brønsted base bifunctional nature of the metal–NH bond, the parent imido complex
promotes heterolysis of H2 and deprotonative N–H cleavage of ammonia to afford the …
