Chemical compound

Tetraethylammonium cyanide is the organic compound with the formula (C2H5)4NCN. It is a "quat salt" of cyanide. It is a colorless, deliquescent solid that is soluble in polar organic media. It is used in the synthesis of cyanometallates.[1]

Tetraethylammonium cyanide is prepared by ion exchange from tetraethylammonium bromide. The corresponding tetraphenylarsonium salt is prepared similarly.[2]

Safety

The salt is highly toxic.
