[Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment. Although many salts of cyanide are highly toxic, ferro- and ferricyanides are less toxic because they tend not to release free cyanide. [1] See more Ferrocyanide is the name of the anion [Fe(CN)6] . Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K4Fe(CN)6. [Fe(CN)6] is a See more Treatment of ferrocyanide with ferric-containing salts gives the intensely coloured pigment Prussian blue (sometimes called ferric ferrocyanide and ferrous ferricyanide). See more Ferrocyanide and its oxidized product ferricyanide cannot freely pass through the plasma membrane. For this reason ferrocyanide has … See more • Common ferrocyanide salts • Fe4[Fe(CN)6]3 • Ag4Fe(CN)6 • Ni4[Fe(CN)6]2 • K4[Fe(CN)6] See more The dominant use of ferrocyanides is as precursors to the Prussian blue pigments. Sodium ferrocyanide is a common anti-caking agent. … See more According to the recommendations of IUPAC, ferrocyanide should be called "hexacyanidoferrate(II)". Cyanides as a chemical class were named because they were discovered in ferrocyanide. Ferrocyanide in turn was named in Latin to mean "blue … See more • Ferricyanide • Blue billy – Prussian blue deposit formed in soils contaminated by effluents of chemical industry See more WebTherefore the Fe(CN) 6 compound is yellow (violet absorbing), and the Fe(NO 3) 2 is green (red absorbing).
