Copper cyanide (Cu(CN)2)

Description:
Copper cyanide, with the chemical formula Cu(CN)₂ and CAS number 4367-08-2, is an inorganic compound that appears as a white to light yellow solid. It is primarily known for its use in electroplating and as a precursor in the synthesis of other copper compounds. The compound is characterized by its coordination complex nature, where copper is coordinated to cyanide ligands, resulting in a linear structure. Copper cyanide is relatively insoluble in water but can dissolve in alkaline solutions, forming soluble copper complexes. It is important to note that copper cyanide is toxic due to the presence of cyanide ions, which can inhibit cellular respiration by binding to cytochrome c oxidase in mitochondria. Safety precautions are essential when handling this compound, as exposure can lead to serious health risks. Additionally, copper cyanide can participate in various chemical reactions, including complexation and redox processes, making it relevant in both industrial applications and environmental chemistry.
