The First mu_6-Peroxide Transition-Metal Complex:[Ni_8(L)_(12)(O_2)]~(2+)

摘要

There continues to be significant attention given to the structural characterization of metal peroxide complexes.The coordination modes observed in such complexes range from peroxide coordination to a single metal center to peroxide acting as a bridging ligand between two,three,four,or six metal ions.Simple mu-peroxo complexes are common;iron,cobalt,and copper dimers are the most prevalent,with recent attention concentrated on Fe-peroxo-Cu complexes as models of the active site of cytochrome c oxidase (Figure 1 a).
