No doubt: The high-quality crystal structure of [Cu(TMG3tren)(O2)]SbF6 (see picture) presents the first unambiguous characterization of a bioinorganic compound in which a dioxygen molecule coordinates end-on to a CuI ion. This species, which is best described as a superoxo copper(II) complex, serves as a model complex for initially formed Cu–O2 adducts present in a variety of active sites of copper enzymes.
