Tetraethylammonium cyanide is the organic compound with the formula [(C H₃CH₂)₄N]CN. It is a "quat salt" of hydrogen cyanide. It consists of tetraethylammonium cations [(CH₃CH₂)₄N]⁺ and cyanide anions CN⁻. This salt is a colorless, deliquescent solid that is soluble in polar organic media. It is used in the synthesis of cyanometallates.^[1]
