Oxidizing noble metals : Pure N 2 O 5 can oxidize elemental gold and palladium. The complex nitrates obtained by these reactions, (NO)[Au(NO 3 ) 4 ], (NO) 2 [Pd(NO 3 ) 4 ], and also the first nitrate of tetravalent platinum, (NO) 2 [Pt(NO 3 ) 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(NO 3 ) 4 ] was elucidated in detail by several methods.
