Iodine cyanide is the inorganic compound with the formula ICN. It is a pseudohalogen composed of iodine and the cyanide group. It is toxic and occurs as white crystals that react slowly with water to form hydrogen cyanide. It is prepared by combining I2 and sodium cyanide in ice-cold water. The product is extracted with ether.

I2 + NaCN → NaI + ICN
