Iridium Dressed To The Nines
The oxidation state of an atom in a molecule is an important means of electron bookkeeping and determining structure and bonding, so the question of just how high oxidation states can go has long piqued chemists’ interest. That ceiling has now reached what was once believed to be an impossibly high level with the preparation of IrO4+, the first example of a molecule with an oxidation state of +9.
“Wow. The discovery that chemical compounds . . .
