Abstract

The first N₂ complex stabilised by N-heterocyclic carbene ligands, Fe(C–N–C)(N₂)₂, has been obtained by the reduction of Fe(C–N–C)Br₂ where C–N–C = 2,6-bis(aryl-imidazol-2-ylidene)pyridine, aryl = 2,6-Prⁱ₂C₆H₃, with Na(Hg); it serves as a convenient precursor for other iron NHC ‘pincer’ complexes of the type Fe(C–N–C)(N₂)L where L = C₂H₄, PMe₃ and Fe(C–N–C)(CO)₂.
