Although +VI has long been the highest experimentally known oxidation state of Ir, the +VIII oxidation state has been produced and identified in low‐temperature noble gas matrices of iridium tetroxide. M. F. Zhou, S. Riedel, and co‐workers describe in their Communication on page 7879 ff. how the compound is formed by co‐depositing Ir atoms with mixtures of O 2 and a noble gas onto a CsI surface at 4–6 K. Theoretical analysis indicates that it is a d 1 species with the formal oxidation state Ir VIII .
