PtCl2 Platinum chloride

Dibenzyl telluride, (C6H5.CH2)2Te, forms a compound with platinum chloride, PtCl2.2(C6H5.CH2)2Te, an orange powder which decomposes in solution with the separation of tellurium, platinum and dibenzyl, but on rapid crystallisation from chloroform is obtained as a microcrystalline powder of greenish-gold colour which darkens and softens at 115° to 120° C.2... 

Foger and Jaeger (70, 71) studied the mechanism of platinum redispersion by chlorine, finding that redispersion occurs by a four-step process. First, one of a number of platinum chloride species forms. For successful redispersion it is critical that conditions be selected such that /J-PtCb forms. This process is influenced by temperature, concentration, and support materials. Second, the volatile / -PtCl2 is transported in the vapor phase. Third, /f-PtCh is readsorbed. 

Platinum chloride forms several additive compounds with carbon monoxide PtClg.CO PtCla.aCO PtCl2.3CO, which are all yellow and which decompose easily by the action of water, separating platinum in a finely divided state and giving cairbon dioxide and hydrochloric acid.

PtCl2, and platiaum tetrachloride [37773-49-2]. Platiaum dichloride exists in an a- and P-form, the latter containing a Pt core and edge-bridging chlorides. Platinum trichloride [25909-39-1], PtCl, contains Pt(II) and Pt(IV) centers. Other haHdes include two bromides, PtBr2 [13455-12-4] and PtBr ... 

The complex PtCl2 is an extremely useful precursor in platinum chemistry.10b The labile benzonitrile ligands can be easily and quantatively replaced by neutral ligands (e.g., amines, phosphines, etc.). On the other hand, the chloride ligands can be substituted by nucleophiles of which an example is given below.
