Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O.A solution of this salt is then treated with sodium salts to precipitate the mixed calcium-sodium salt CaNa 2 [Fe(CN) 6] 2, which in turn is treated with sodium carbonate to give the tetrasodium salt.
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. [Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment.
2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl. This reaction can be used to remove potassium hexacyanidoferrate(II) from a solution. [citation needed] A famous reaction involves treatment with ferric salts, most commonly Iron(III) chloride, to give Prussian blue. In the reaction with Iron(III) chloride, producing Potassium chloride as a ...

A well known couple is [Fe(CN) 6] 3−/4−. Mn(IV), Mn(III), and Mn(II) are known for hexacyanomanganate. Mn(IV), Mn(III), and Mn(II) are known for hexacyanomanganate. Few unidentate ligands allow similar redox transformations wherein both members of the redox couple are observable in solution.
