| Abstract: | In analogy to peroxide, disulfide is an oxidant as well as a reductant. Accordingly, as a ligand of a reducing metal center, low-energy MLCT transitions can occur, while with oxidizing metals low-energy LMCT transitions should be observed. Such MLCT and LMCT excitations are expected to induce redox reactions. The complexes CpFe(II)(CO)2]2μ-S2 (Cp C5H5) and {Fe(III)(CN)5]2μ-S2}6 ? are suitable examples to explore this behavior. |
