What is fecn6?
Ferricyanide is the anion [Fe(CN)6]3−. It is also called hexacyanoferrate(III) and in rare, but systematic nomenclature, hexacyanidoferrate(III). The most common salt of this anion is potassium ferricyanide, a red crystalline material that is used as an oxidant in organic chemistry.

What is ferric ferrocyanide?
Ferric ferrocyanide is an iron-based inorganic colorant also known as Prussian blue; one of the first synthetic pigments.
Is Prussian blue inorganic?
The pigment Prussian blue consists of iron cations, cyanide anions, and water. In addition to having as many as 16 molecules of water per formula unit, the compound usually contains inorganic impurities, which can affect its color.
Why is ferrocyanide Coloured?
The colour of a complex compound is due to unpaired electrons. As per crystal field theory, K4[Fe(CN)6] has no unpaired electrons so it has to be colourless.
What is the oxidation number of ferrocyanide?
-4
the groups ferrocyanide have the charge -4, given from 6 ions CN− with charge -1 and a atom of iron with charge +2.
How is potassium ferrocyanide made?
Potassium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca2[Fe(CN)6]·11H2O.
What is the theoretical capacity of ferric ferrocyanide 6?
Optimized composition with high sodium content and negligible water content, R-Na 1.92 Fe 2 (CN) 6, delivered a high capacity, 160 mAhg −1, close to theoretical capacity (170 mAhg −1) at an average potential of 3.1 V ( Fig. 4 F) ( Wang et al., 2015 ).
What is the structure of ferric ferrocyanide Prussian blue?
Ferric Ferrocyanide Prussian blue has a basic cubic structure consisting of alternating iron (II) and iron (III) located on a face centered cubic lattice (Fig. 13.1), in such a way that the iron (III) ions are surrounded octahedrically by nitrogen atoms, and iron (II) ions are surrounded by carbon atoms.
What is the empirical formula for ferric hexacyanoferrate ( II )?
Ferric hexacyanoferrate (II), known as Prussian blue, has the empirical formula Fe 4 [Fe (CN) 6] 3. It was probably synthesized for the first time by the paint maker Diesbach in Berlin in 1704, and it was one of the first synthetic pigments. A number of different, even if chemically related compounds, are named Prussian blue.
What kind of ferrocyanide to use on bone marrow smear?
A Prussian blue (acidic potassium ferrocyanide) iron stain is commonly used on the bone marrow aspirate smear. Figure 14.16 illustrates normal iron, absence of iron, and increased iron stores in aspirate smears.
