Chemical compound
Potassium dicyanoargentate is an inorganic compound with the formula KAg(CN)2. A white solid, it is the K+ salt of the linear coordination complex [Ag(CN)2]−. It forms upon treatment of virtually any silver salt with two equivalents of potassium cyanide.
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]
