Sodium tetrachloropalladate is an inorganic compound with the chemical formula Na2PdCl4. The compound crystallizes from water as a reddish-brown trihydrate (Na2PdCl4·3H2O), which is the commercially available form.[1]

Preparation

This salt, and the analogous alkali metal salts of the form M2PdCl4, may be prepared simply by reacting palladium(II) chloride with the appropriate alkali metal chloride in aqueous solution.[2] Palladium(II) chloride is insoluble in water, whereas the product dissolves:

PdCl2 + 2 MCl → M2PdCl4

This compound may further react with phosphines to give phosphine complexes of palladium.

An alternative method of preparing such phosphine complexes is to break up the coordination polymer of palladium(II) chloride into reactive, monomeric acetonitrile or benzonitrile complexes,[3] followed by reaction with phosphines.[2]
