Description
Summary:Oxidizing noble metals: Pure N2O5 can oxidize elemental gold and palladium. The complex nitrates obtained by these reactions, (NO)[Au(NO3)4], (NO)2[Pd(NO3)4], and also the first nitrate of tetravalent platinum, (NO)2[Pt(NO3)6] (see picture for the anion: Pt gray, N green, O blue), have the potential to act as precursors owing to their high thermolability. The thermal decomposition of (NO)[Au(NO3)4] was elucidated in detail by several methods.
