Uses and reactions

KAg(CN)₂ is significant adventitious product of gold mining using cyanide as an extractant.^[1]

It can be used in silver plating, as a bactericide, and in the manufacture of antiseptics.^[2]

It forms a variety of coordination polymers, a property that exploits the bridging tendency of the cyanide ligand.^[3]
