Copper(I) iodide, like most binary (containing only two elements) metal halides, is an inorganic polymer.It has a rich phase diagram, meaning that it exists in several crystalline forms.
A typical catalyst is formed from copper(I) iodide and phenanthroline. The reaction is an alternative to the Buchwald–Hartwig amination reaction. Aryl iodides are more reactive arylating agents than are aryl chlorides, following the usual pattern.
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 ...
Ullmann condensation - copper-promoted conversion of aryl halides to ethers, also developed by Fritz Ullmann; Copper(I) thiophene-2-carboxylate, a copper reagent used in the Ullmann reaction; Wurtz–Fittig reaction, a similar reaction useful for alkylbenzenes synthesis
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).

Upon heating the solid to 146 °C, this material adopts the alpha-polymorph. In this form, the iodide ions form a rigid cubic framework, and the Ag+ centers are molten. The electrical conductivity of the solid increases by 4000x. Similar behavior is observed for copper(I) iodide (CuI), rubidium silver iodide (RbAg 4 I 5), [9] and Ag 2 HgI 4.
Copper hydride is an inorganic compound with the chemical formula CuH n where n ~ 0.95. [3] It is a red solid, rarely isolated as a pure composition, that decomposes to the elements. [4] Copper hydride is mainly produced as a reducing agent in organic synthesis and as a precursor to various catalysts. [5]
