Sodium ferrocyanide is the sodium salt of the coordination compound of formula [Fe(CN) 6] 4−. In its hydrous form, Na 4 Fe(CN) 6 · H 2 O (sodium ferrocyanide decahydrate), it is sometimes known as yellow prussiate of soda. It is a yellow crystalline solid that is soluble in water and insoluble in alcohol. The yellow color is the color of ...
[Fe(CN) 6] 3− consists of a Fe 3+ center bound in octahedral geometry to six cyanide ligands. The complex has O h symmetry. The iron is low spin and easily reduced to the related ferrocyanide ion [Fe(CN) 6] 4−, which is a ferrous (Fe 2+) derivative. This redox couple is reversible and entails no making or breaking of Fe–C bonds:
Ferrocyanide is the name of the anion [Fe() 6] 4−.Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6.
Prussian white, also known as Berlin white or Everett's salt, is the sodium end-member of the totally reduced form of the Prussian blue in which all iron is present as Fe(II). It is a sodium hexacyanoferrate of Fe(II) of formula Na 2 Fe[Fe(CN) 6]. [29] Its molecular weight value is 314 g/mol. [29]

Potassium hexacyanidoferrate(II) finds many niche applications in industry. It and the related sodium salt are widely used as anticaking agents for both road salt and table salt. The potassium and sodium hexacyanidoferrates(II) are also used in the purification of tin and the separation of copper from molybdenum ores.
Ammonium hexacyanoferrate(II) is an inorganic chemical compound with the chemical formula (NH 4) 4 [Fe(CN) 6]. [1] [2] Synthesis.
Prussian blue, also known as potassium ferric hexacyanoferrate, is used as a medication to treat thallium poisoning or radioactive caesium poisoning. [ 1 ] [ 2 ] For thallium it may be used in addition to gastric lavage , activated charcoal , forced diuresis , and hemodialysis .
