Sodium hexachloroplatinate
Chemical compound
Sodium hexachloroplatinate(IV), the sodium salt of chloroplatinic acid, is an inorganic compound with the formula Na2[PtCl6], consisting of the sodium cation and the hexachloroplatinate anion. As explained by Cox and Peters, anhydrous sodium hexachloroplatinate, which is yellow, tends to form the orange hexahydrate upon storage in humid air. The latter can be dehydrated upon heating at 110 °C.[1]
The compound is utilised as the most common chemical shift reference in platinum-195 NMR spectroscopy, relative to which the shifts of other platinum species in solution are reported.[2]
