Revising the highest oxidation states of the 5d elements: The case of iridium(+VII)

Abstract

(Graph Presented) The magnificent VII? High-level quantum chemical calculations show iridium in oxidation state +VII to be a viable synthetic target, whereas higher oxidation states of this element appear unlikely. With the theoretically predicted IrVII and HgIV included, a linear descent of maximum oxidation states from Os to Hg is found in the 5d series (see Figure: • highest experimentally known values, ▲ probably incorrect experimental assignments, and □ most likely predicted values). © 2006 Wiley-VCH Verlag GmbH & Co.
