Prussian blue is regarded as a compound of three equivalents of ferroeyanogen with two of iron, and its composition is therefore expressed by the formula 8 Cfy -j- 2 Fea, or Fe, Cys, It is formed whenever a salt of sesquioxide of iron is added to a soluble metallio ferrocyanide. The usual method is to precipitate a solution of sesquiehloride or sesquinitrate of iron by ferrocyanide of potassium and In point qf fact a very important part of its manufacture consists in the preparation of this latter salt, which will now be described.

The remaining interstitial or "zeoiitic" water in the cubic sites has been omitted for clarity, as hove most of the cyanide ious. In addition, some of the cyanide ions are replaced by water molecules coordinated to iron(III), and there are also vacancies in the structure. [Modified from Buser, H. J. Schwarzenbach, D. Petter, W.

Cyanide Iron Blues. Cyanide iron blue, also known as Prussian blue, is one of die oldest industrially produced, inorganic pigments. Chemically, cyanide iron blues are based on the Fe21 [Fe31 (CN)g]J anion. The charge is balanced by sodium, potassium, or ammonium cations. 

All of the [Fe(CN) J4- salts may be considered salts of ferrocyanic acid or tetrahydrogen hexakiscyanoferrate [17126-47-5], H4[Fe(CN)J, a strongly acidic, air-sensitive compound. It is soluble in water and alcohol but is insoluble in ether. It can be prepared by precipitation of an etherate by adding ether to a solution of [Fe(CN) J4"" that was acidified with concentrated sulfuric acid. Removal of the ether of solvation affords a white powder which is stable when dry but slowly turns blue in moist air because of Prussian Blue formation. 

Prussian Blue. Reaction of [Fe(CN)6]4 with an excess of aqueous iron(III) produces the finely divided, intensely blue precipitate Prussian Blue [14038-43-8] (tetrairon(III) tris(hexakiscyanoferrate)), Fe4fFe(CN)6]. Prussian Blue is identical to Turnbull s Blue, the name which originally was given to the material produced by reaction of [Fe(CN)6]3 with excess aqueous iron(II). The solid contains or has absorbed on its surface a laige and variable number of water molecules, potassium ions (if present in the reaction), and iron(III) oxide. The iron(II) centers are low spin and diamagnetic iron(III) centers are high spin. Variations of composition and properties result from variations in reaction conditions. Rapid precipitation in the presence of potassium ion affords a colloidal suspension of Prussian Blue [25869-98-1] which has the approximate composition IvFe[Fe(CN) J. Prussian Blue compounds are used as pigments in inks and paints and its formation on sensitized paper is utilized in the production of blueprints.
