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 ...
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.
Cyanogen azide is a chemical compound with the chemical formula C N 4, or more precisely − N=N + =N−C≡N. It is an azide compound of carbon and nitrogen. It is an oily, colourless liquid at room temperature. [2] It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form.

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 ...
Prussian blue (also known as Berlin blue, Brandenburg blue, Parisian and Paris blue) is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. It has the chemical formula Fe 3+ 4 [Fe 2+ 6] 3.
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: [Fe(CN) 6] 3− + e − ⇌ [Fe(CN) 6] 4−. This redox couple is a standard in electrochemistry.
Typical nitrile ligands are acetonitrile, propionitrile, and benzonitrile.The structures of [Ru(NH 3) 5 (NCPh)] n+ have been determined for the 2+ and 3+ oxidation states. Upon oxidation the Ru-NH 3 distances contract and the Ru-NCPh distances elongate, consistent with amines serving as pure-sigma donor ligands and nitriles functioning as pi-acceptors.
