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 ...
H 2 PtCl 6 → PtCl 4 + 2 HCl. A purer product can be produced by heating under chlorine gas at 250 °C. [4] 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 ...
trans-Dichlorodiammineplatinum(II) is the trans isomer of the coordination complex with the formula trans-PtCl 2 (NH 3) 2, sometimes called transplatin. [1] It is a yellow solid with low solubility in water but good solubility in DMF. The existence of two isomers of PtCl 2 (NH 3) 2 led Alfred Werner to propose square planar molecular geometry. [2]
Zeise's dimer, [(η 2-C 2 H 4)PtCl 2] 2, derived from Zeise's salt by elimination of KCl followed by dimerisation. COD-platinum dichloride, (cyclooctadiene)PtCl 2, derived from platinum(II) chloride and 1,5-cyclooctadiene, is a common platinum(II) alkene complex. Many other ethylene complexes have been prepared.
Some common examples of platinum precursors include potassium hexachloroplatinate (K 2 PtCl 6) or platinous chloride (PtCl 2) [1] [8] Different combinations of precursors, such as ruthenium chloride (RuCl 3) and chloroplatinic acid (H 2 PtCl 6), have been used to synthesize mixed-metal nanoparticles [9] Some common examples of reducing agents ...
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
Pt 4+ (aq) + 6 Cl − (aq) → [PtCl 6] 2− (aq) Experimental evidence reveals that the reaction of platinum with aqua regia is considerably more complex. The initial reactions produce a mixture of chloroplatinous acid (H 2 [PtCl 4]) and nitrosoplatinic chloride ([NO] 2 [PtCl 4]). The nitrosoplatinic chloride is a solid product.
