摘要：
A state of eight: Iridium atoms insert into dioxygen to form iridium dioxide molecules in solid noble-gas matrices. Annealing allows formation of the iridium dioxide superoxide complex [(η1-O2)IrO 2], which isomerizes under IR irradiation to the iridium dioxide peroxide complex [(rfO2)IrO2]. These complexes photochemically rearrange to the more stable iridium tetroxide molecule with an iridium oxidation state of - VIII (see scheme; Ir black, O red). © 2009 Wiley-VCH Verlag GmbH & Co.
