WebAn international team of scientists has made a compound containing iridium in the +9 oxidation state – something that has been predicted by theoretical models but never formed experimentally before.. Until now, the highest oxidation state any element was shown to exist at was +8. Iridium, with nine valence electrons, can exist in a variety of … Web1 de mar. de 2009 · The highest oxidation state of iron characterized experimentally is Fe(VI), in form of various salts (or solutions) of the [FeO 4] 2− ion [31], and very recently in form of a six-coordinated nitride complex [155]. The latter was characterized by Mössbauer and X-ray absorption spectroscopy.
The highest known oxidation state is reported to be +9, displayed by iridium in the tetroxoiridium (IX) cation ( IrO+ 4 ). [1] It is predicted that even a +10 oxidation state may be achieved by platinum in tetroxoplatinum (X), PtO2+ 4. [2] The lowest oxidation state is −5, as for boron in Al3BC.
