Interactions which may cause the disproportionation of noble-metal complexes can be suppressed inthe gas phase. Under such circumstances, it is shownthat gold(II) is capable of forming stable coordinationcomplexes similar to those seen for Cu(II) and Ag(II).
Interactions which casue the disproportionation of noble-metal oxidation states can suppressed in the gas phase. Under such circumstances, it is shown that gold(II) is capable of forming stable coordination complexes similar to those seen for Cu(II) and Ag(II).
