Transformation of an [Fe(η^2-N_2H_3)]^+ Species to π-Delocalized [Fe_2(μ-N_2H_2)]^(2+/+) Complexes
Abstract
A monomeric Fe(η^2-N_2H_3) species has been prepared, and exposure to oxygen yields a diiron complex that features five-coordinate iron centers and an activated bridging diazene ligand (see picture; C gray, N blue, Fe black, P red, O green). Structural, theoretical, and spectroscopic data for the redox pair [Fe_2(μ-N_2H_2)]^(2+/+) are consistent with 4-center, 4-electron π-delocalized bonding across the Fe-NH-NH-Fe core that finds analogy in butadiene and the butadiene anion.
