Copper(II) trifluoroacetate is the trifluoroacetate of divalent copper with the chemical formula Cu(CF3COO)2. It exists as the anhydride, hydrate and adducts of other solvents. The hydrate begins to lose two waters of crystallisation at 108 °C, and loses all crystal water at 173 °C to form the anhydrous form. This begins to decompose at 220 °C.[6]
Copper trifluoroacetate can be obtained by reacting trifluoroacetic acid with copper oxide, copper hydroxide or basic copper carbonate. Acetone can replace the water molecules in copper trifluoroacetate hydrate, and under reduced pressure conditions, the acetone can be removed to obtain anhydrous material.[1]
The copper atoms of copper trifluoroacetate can be coupled with ammonia molecules or water molecules, and can also form adducts with some organic molecules, such as [Cu(H2O)3(OOC-CF3)2]·2C4H8O2.[7]
