From amido to imido : A dinuclear amido‐bridged iridium complex promotes the dehydrogenation of alcohols, affording unusual mixed amido/imido Ir 4 and bis(imido) Ir 3 clusters. Theoretical calculations suggest that bridging μ‐NH 2 linkages are crucial to achieve the formation of hydrido amine diiridium species, as a result of a concerted net hydrogen transfer through a proposed eight‐membered dimetallacycle.
