If excess acids are removed, PtCl 4 crystallizes from aqueous solutions in large red crystals of pentahydrate PtCl 4 ·5(H 2 O), [5] which can be dehydrated by heating to about 300 °C in a current of dry chlorine. The pentahydrate is stable and is used as the commercial form of PtCl 4. Treatment of PtCl 4 with aqueous base gives the [Pt(OH) 6 ...
Chloropentammineplatinum chloride is an inorganic compound with the formula [PtCl(NH 3) 5]Cl 3. It is a chloride salt of the coordination complex [PtCl(NH 3) 5] +. It is a white, water soluble solid. The compound is prepared by treating potassium hexachloroplatinate with aqueous ammonia: [1] K 2 PtCl 6 + 5 NH 3 → [PtCl(NH 3) 5]Cl 3 + 2 KCl

β-PtCl 2 is prepared by heating chloroplatinic acid to 350 °C in air. [4] H 2 PtCl 6 → PtCl 2 + Cl 2 + 2 HCl. This method is convenient since the chloroplatinic acid is generated readily from Pt metal. Aqueous solutions of H 2 PtCl 6 can also be reduced with hydrazinium salts, but this method is more laborious than the thermal route of Kerr ...

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. Although often written in shorthand as H 2 PtCl 6, it is the hydronium (H 3 O +) salt of the ...
