Hexacyanoferrate, ferric

Ferric ferrocyanide—Cl Pigment Blue 27, Cl No. 77510. The color additive ferric ferrocyanide is a ferric hexacyanoferrate is a pigment characterized by the stmctural formula Fe4[Fe(CN)g]2ArH20, which may contain small amounts of ferric sodium ferrocyanide and ferric potassium ferrocyanide. ... 

Prussian blue, or ferric hexacyanoferrate, is definitely one of the most ancient coordination materials. The earliest announcements were from the very beginning of the eighteenth century [1, 2], However, a quite recent investigation by Neff [3], that Prussian blue forms electroactive layers after electrochemical or chemical deposition onto the electrode surface, has opened a new area in fundamental investigation of this unique inorganic polycrystal.

Toxico-kinetic studies showed, that the adsorption of iron blue pigments is very low. Following intravenous injection of a Fe radio-labeled iron blue pigment, the Fe(CN)6- ion was rapidly and virtually completely excreted with the urine. After oral administration of ferric hexacyanoferrate ( Fe) approx. 2% of the labeled hexacyano-ferrate ion was adsorbed by the gastro-intestinal tract [3.199]. Most of the substance is excreted with the feces [3.200] and there was no evidence of its decomposition. 

In human volunteers who received 1.5 or 3.0 g ferric hexacyanoferrate(II) for up to 22 days apart from a slight obstipation no effects were reported [3.211, 3.212].

Fe + may also be characterized by the reaction it gives with the hexacyano-ferrate(II) anion [Fe(CN)6]" formerly called the ferrocyanide ion. A deep blue precipitate called Berlin blue or Prussian blue forms. It is interesting to notice that the ferrocyanide ion is a complex itself. The structure of ferric hexacyanoferrate-(II), namely, Fe4[Fe(SCN)6]3, has been ascribed to Prussian blue. 

As a result, ferric hexacyanoferrate(II), that is, Prussian blue, is formed as in the characterization of Fe +. The analysis of both precipitates obtained in the preceding two characterizations proves that they are identical.
