Question:
The geometry of complex ion $[ {Fe(CN)_6}]^{4-}$ is
The geometry of complex ion $[ {Fe(CN)_6}]^{4-}$ is
Updated On: Aug 15, 2022
- trigonal pyramidal
- octahedral
- square planar
- tetrahedral.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$[ {Fe(CN)_6}]^{4-}$
$ {Fe(26)} : 3d^6\, 4s^2$
$ {Fe^{2+}}$
$ {CN^-}$ being a strong field ligand causes pairing of electrons

Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
