Activation of Molecular Oxygen by Anionic Gold Clusters

Activation of Molecular Oxygen by Anionic Gold Clusters: Thumbnail image of graphical abstract

A golden opportunity: molecular oxygen is found to be converted into a superoxo (O2) species upon complexation to gold-cluster anions containing an even number of Au atoms. Vibrational spectra (see scheme) reveal small variations in the extent of O[BOND]O bond activation dependent upon the electron affinity of the parent cluster.
