- In K3[Fe(CN)6] O.S of Fe can be calculated as - x + (6 * -1) = -3 x = +3- Similarly in K3[Fe(F)6] O.S of Fe -x + (6 * -1) = -3x = +3So the configuration of Fe^+3 = 3d^5Now in K3[Fe(CN)6] CN- being a strong field ligand pairs up the d^5 electrons and leads to (t2g^5 eg^0) d configuration.
potassium hexacyanoferrate (III)
Hence the oxidation state of Fe in K3[Fe(CN)6] is +3.
Explain that K4Fe(CN)6 is diamagnetic while K3Fe(CN)6 is paramagnetic.
Thus, Fe3+ has an unpaired electron. Thus, the complex will be a paramagnetic substance.
[Fe(CN)6]3 has d5 configuration. It is inner orbital or low spin complex. It undergoes d2sp3 hybridization. This results in octahedral geometry.
- EAN rule. Effective atomic number (EAN) in a complex is defined as the total number of electrons present around the central metal ion. ...
- EAN formula. EAN= Z – x + 2nL. ...
- [Cu(NH3)4] 2+
effective atomic number (EAN), number that represents the total number of electrons surrounding the nucleus of a metal atom in a metal complex. It is composed of the metal atom's electrons and the bonding electrons from the surrounding electron-donating atoms and molecules.
How is EAN value calculated?
EAN = Atomic number of the metal +(Number of ligands x electrons donated by each ligand) - positive oxidation state of the metal.
Hence K3[Fe(CN)6] more stable because Fe3+ is smaller in size and has higher charge than Fe2+.

[K4Fe(CN)6] is diamagnetic in nature because electronic congiguration of Fe+2 is 1s22s2p63s2p63d64s0.
The electron configuration of ferrocyanide [Fe(CN)6]4− is (t2g)6 while the configuration of ferricyanide [Fe(CN)6]3− is (t2g)5. These orbitals are pi-bonding in nature, which means increased electron density will result in increased electron donation from the metal d orbitals to the ligand π* orbitals.
Van't Hoff factor of centimolal solution of K3[Fe(CN)6] is 3.333.
“Potassium ferrocyanide is an inorganic compound with the chemical formula K4Fe(CN)6.
In case of [NiCl4] 2−, Cl− ion is a weak field ligand. Therefore, it does not lead to the pairing of unpaired 3d electrons. Therefore, it undergoes sp3 hybridization. Since there are 2 unpaired electrons in this case, it is paramagnetic in nature.
“Potassium ferrocyanide is an inorganic compound with the chemical formula K4Fe(CN)6.
Potassium ferrocyanide is used in the production of wine and citric acid. In the EU, ferrocyanides (E 535–538) were, as of 2017, solely authorised in two food categories as salt substitutes. Kidneys are the organ for ferrocyanide toxicity. It can also be used in animal feed.

What is K3 Fe C2O4 3 Iupac name?
Potassium trioxalato Ferrate(III) =K3[Fe(C2O4)3]
Explanation: The central atom in the compound K4[Fe(CN)6] is Iron, and it is present in the anionic entity, so the name will be ferrate.
