Potassium Tetrachlorocuprate(II)

Potassium Tetrachlorocuprate(II) is an inorganic compound with the formula K 2 CuCl 4, which can be found as anhydrous or as a dihydrate. It can be found naturally around volcanic vents as the mineral mitscherlichite.

Synthesis
Potassium Tetrachlorocuprate(II) can be created by making a 2:1 molar ratio solution of potassium chloride and copper(II) chloride with a high concentration of HCl and allowing it to evaporate.

Reactions
Potassium Tetrachlorocuprate(II) dihydrate decomposes into potassium chloride and potassium trichlorocuprate(II) when heated to 93 °C.
