CuF2

Copper(II) fluoride, also known as cupric fluoride, has the chemical formula CuF2. It is an inorganic compound. At room temperature and pressure, CuF2 exists as a white crystalline solid. It is an ionic compound composed of copper cations in the +2 oxidation state (Cu2+) and fluoride anions (F-). The structure of copper(II) fluoride is a rutile-type crystal lattice.

CuF2 is sparingly soluble in water. When dissolved in water, it forms a blue solution. This compound is an oxidizing agent. It can react with certain substances, particularly reducing agents. Copper(II) fluoride is a semiconductor.

Copper(II) fluoride is prepared by several methods. One common method involves the reaction of copper(II) oxide or copper(II) hydroxide with hydrofluoric acid. Another method is the direct reaction of copper metal with fluorine gas at elevated temperatures.

CuF2 finds some limited applications. It has been explored for use in solid-state electrolytes in batteries. It can also serve as a catalyst in certain chemical reactions. Due to its properties, it is primarily encountered in research and specialized industrial processes rather than widespread consumer applications.
