Iodine cyanide, ICN, is a pseudohalogen composed of iodine and the cyanide group. It is toxic, and occurs as white crystals^{[citation needed]} that melt at 146−147 °C. It reacts with water to form hydrogen cyanide. Synthesis of ICN is relatively easy using I₂ and NaCN in ice-cold water with subsequent ether extraction.
