Potassium tetrachloropalladate(II) is an inorganic compound with the chemical formula K2PdCl4.[5][6] It is a dark brown solid, forming tetragonal crystals.
Potassium tetrachloropalladate(II) can be prepared by passing chlorine through a palladium black suspension in a concentrated potassium chloride solution:
- Pd + Cl2 + 2KCl → K2[PdCl4]
It can also be prepared by mixing concentrated solutions of palladium(II) chloride and potassium chloride:[7]
- PdCl2 + 2KCl → K2[PdCl4]
It forms in the decomposition of potassium hexachloropalladate(IV):
- K2[PdCl6] → K2[PdCl4] + Cl2
