WebThe oxidation state of gold in its compounds ranges from −1 to +5, but Au (I) and Au (III) dominate its chemistry. Au (I), referred to as the aurous ion, is the most common oxidation state with soft ligands such as thioethers, thiolates, and organophosphines. Au (I) compounds are typically linear. evan twiford missoula
