Platinum Chloride (PtCl2)-Crystal Pieces

Platinum Chloride (PtCl2)-Crystal Pieces introduce:

Characteristic




Platinum(II) chloride is the chemical compound PtCl2. It is an important precursor used in the preparation of other platinum compounds. It exists in two crystalline forms, but the main properties are somewhat similar: dark brown, insoluble in water, diamagnetic, and odorless.




Chemical formula：PtCl2

Molar mass： 265.99 g/mol

Appearance： olive green crystals

Density： 6.05 g/cm3, solid

Melting point： 581 °C (1,078 °F; 854 K)

Boiling point： decomposes

Solubility in water：insoluble

Solubility： insoluble in alcohol, ether

soluble in HCl, ammonia

Magnetic susceptibility (χ)：−54.0·10−6 cm3/mol

Crystal structure：hexagonal




Application

Most reactions of PtCl2 proceed via treatment with ligands (L) to give molecular derivatives. 




Sometimes, such reactions can be deceptive. Addition of ammonia gives initially "PtCl2(NH3)2", but this material is in fact Magnus's green salt, [PtCl4][Pt(NH3)4].
