Copper(I) iodide reacts with mercury vapors to form brown copper(I) tetraiodomercurate(II): 4 CuI + Hg → (Cu +) 2 [HgI 4] 2− + 2 Cu. This reaction can be used for the detection of mercury since the white CuI to brown Cu 2 [HgI 4] color change is dramatic. Copper(I) iodide is used in the synthesis of Cu(I) clusters such as [Cu 6 I 7] −. [10]
Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c ...

Some copper proteins form oxo complexes, which also feature copper(III). [20] With tetrapeptides, purple-colored copper(III) complexes are stabilized by the deprotonated amide ligands. [21] Complexes of copper(III) are also found as intermediates in reactions of organocopper compounds. [22] For example, in the Kharasch–Sosnovsky reaction.
