Calculate CFSE of the following complexes : [Fe (CN)_6]^ {4-}-0.4 ...
In [F e (C N) 6] 4 −, iron has 3 d 6, 4 s 2 system in ground state but in excited state it loses two electrons in the formation of ions and two electrons from 4 s, so thus Cobalt gets 3 d 6 configuration. Now it is of low spin complex due to C N ligands so all 6 electrons will go to t 2 g orbitals. and 0 electrons will be in e g orbital. By ...
[Fe (CN)_6]^ {-3} is low spin complex but [Fe (H_2O)_6]^ {+3
The octahedral complex ions [F e C l 6] 3 − and [F e (C N) 6] 3 − are both paramagnetic but the former is high spin and the latter is low spin. In the l ow spin complex, [F e (C N) 6] 3 − has the d-configuration as:
The name of complex ion, [Fe(CN)_6]^{3-} is: Hexacyanoiron (III
In the given complex there are 6 Cyanide ligands and the oxidation number of Fe is M-6= -3 This implies Fe is in +3 oxidation state and Hence the IUPAC name of the complex should be hexacyanidoferrate(III).Hence option D is correct.
For the complex ion [Fe(CN)_6]^{3-}, state:(i) the of ... - Toppr
In [F e (C N) 6] − 3 complex C N is a strong field ligand therefore will form low spin complex by using inner 3d-orbitals. Since it has octahedral geometry as there are 6 ligands, so its hybridization will be d 2 s p 3.
[Fe (CN)_ {6}]^ {4-} and [Fe (H_ {2}O)_ {6}]^ {2+} are of different ...
In both complexes, iron has +2 oxidation state with outer electronic configuration of 3 d 6 and four unpaired electrons. In presence of weak filed water ligand, these unpaired electrons do not pair up.
The chemical formula of iron(III) hexacyanoferrate(II) is: - Toppr
We proceed from left to right, iron (III) means F e 3 +, hexacyano means 6 C N − ions are present and ferrate (II) means F e 2 + is the central metal atom. So, the complex ion is [ F e ( C N ) 6 ] 4 − and the counter ion is F e 3 + .

Discuss the nature of bonding in [Fe(CN)_6]^{-4} on the basis
d 2 s p 3 hybridized orbitals of F e 2 + are 6 electron pairs are from C N − ion occupy the six hybrid d 2 s p 3 orbitals. Hence, the geometry of the complex is octahedral and the complex is diamagnetic (as there are no unpaired electrons).
The stable complex species is:[Fe(C_2O_4)_3]^{3-}[Fe(CN)_6]^{4
Thus the [F e (C N) 6] 4 − complex containing F e 2 + ion is least stable. The stability of the complex also depends on the basic strength of the ligand. Greater is the base strength of the ligand, greater is the stability of the complex.
[Fe(CN)_6]^{3-} is stable than [Fe(CN)_6]^{4-}.TrueFalse - Toppr
The oxidation state of central Fe atom in [F e (C N) 6] 3 − and [F e (C N) 6] 4 − is +3 and +2 respectively. Higher is the oxidation state of the central metal atom in the complex, higher is the stability. Hence, [F e (C N) 6] 3 − is more stable than [F e (C N) 6] 4 −
