The synthesis of [2Fe–2E] (E = S and Se) complexes supported by an N-alkyl,N′-aryl-β-diketiminate ligand is described. The [2Fe–2S] model compound has an unusually long Fe⋯Fe distance, but the equivalent distance in the [2Fe–2Se] compound is comparable to those reported in the literature. These model compounds display varying electron transfer capabilities, which were elucidated through electronic spectroscopy and electrochemical analysis. Kinetic data and activation parameters suggest the formation mechanism of the [2Fe–2S] compound. Additionally, to probe the possible sulfur-transfer mechanism of [2Fe–2S] clusters, atom transfer reactivity was pursued.
