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.
