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 ...
Bis(triphenylphosphine)platinum chloride is a metal phosphine complex with the formula PtCl 2 [P(C 6 H 5) 3] 2. Cis- and trans isomers are known. The cis isomer is a white crystalline powder, while the trans isomer is yellow. [3] Both isomers are square planar about the central platinum atom. The cis isomer is used primarily as a reagent for ...
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.
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 ...
The complex is so poorly soluble that this step is employed in the isolation of platinum from ores and recycled residues. [3] As analyzed by X-ray crystallography, the salt crystallizes in a cubic motif reminiscent of the fluorite structure. The [PtCl 6] 2− centers are octahedral. The NH 4 + centers are hydrogen bonded to the chloride ligands ...
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]
Dissociation of the chloride is favored inside the cell because the intracellular chloride concentration is only 3–20% of the approximately 100 mM chloride concentration in the extracellular fluid. [21] [22] The water molecule in cis-[PtCl(NH 3) 2 (H 2 O)] + is itself easily displaced by the N-heterocyclic bases on DNA. Guanine preferentially ...
