The ions , in octahedral field of weak field ligands will have configuration
t2g4e0g
t2g2e2g
t2g3e1g
t2g1e3g
As we learnt in
Weak field Ligand -
These are the ligands which do not pair the electron in inner d-orbital.
- wherein
For example: etc
In Octahedral field of d4 electrons, in case of weak field Ligands, we have
