摘要
A golden opportunity: Molecular oxygen is found to be converted into a superoxo (O 2 -) 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-O bond activation dependent upon the electron affinity of the parent cluster. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
