Both biological and industrial nitrogen reduction catalysts activate N2 at multinuclear binding sites with constrained Fe-Fe distances. This contrasts with molecular diiron systems, which routinely form linear N2 bridges to minimize steric interactions. Model compounds that capture the salient geometric features of N2 binding by the nitrogenase enzymes and Mittasch catalysts would contribute to understanding their high N2-reduction activity. It is shown in the present study that use of a geometrically flexible, dinucleating macrocycl
