2. Adams' catalyst - Wikipedia

   en.wikipedia.org/wiki/Adams'_catalyst

   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 ...

   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.

5. Platinum (IV) chloride - Wikipedia

   en.wikipedia.org/wiki/Platinum(IV)_chloride

   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 ...
