The first published preparation was reported by V. Voorhees and Roger Adams. [2] The procedure involves first preparing a platinum nitrate which is then heated to expel nitrogen oxides. [3] H 2 PtCl 6 + 6 NaNO 3 → Pt(NO 3) 4 + 6 NaCl (aq) + 2 HNO 3 Pt(NO 3) 4 → PtO 2 + 4 NO 2 + O 2. The resulting brown cake is washed with water to free it ...
Hexaammineplatinum(IV) chloride is the chemical compound with the formula [Pt(NH 3) 6]Cl 4. It is the chloride salt of the metal ammine complex [Pt(NH 3) 6] 4+. The cation features six ammonia (called ammines in coordination chemistry) ligands attached to the platinum(IV) ion. It is a white, water soluble solid.
Chloroplatinic acid (also known as hexachloroplatinic acid) is an inorganic compound with the formula [H 3 O] 2 [PtCl 6](H 2 O) x (0 ≤ x ≤ 6). A red solid, it is an important commercial source of platinum, usually as an aqueous solution.

Typical of Pt(IV), the metal centers adopt an octahedral coordination geometry, {PtCl 6}. This geometry is achieved by forming a polymer wherein half of the chloride ligands bridge between the platinum centers. Because of its polymeric structure, PtCl 4 dissolves only upon breaking the chloride bridging ligands. Thus, addition of HCl give H 2 ...

Platinum(IV) oxide, PtO 2, also known as "Adams' catalyst", is a black powder that is soluble in potassium hydroxide (KOH) solutions and concentrated acids. [41] PtO 2 and the less common PtO both decompose upon heating. [13] Platinum(II,IV) oxide, Pt 3 O 4, is formed in the following reaction: 2 Pt 2+ + Pt 4+ + 4 O 2− → Pt 3 O 4
