As we discussed in the concept
Inner sphere complex -
Complexes in which (n-1)d orbitals are used in hyberdisation.
- wherein
For example:
Strong Field Ligand -
These are the ligands which pair the electron in inner d-orbital and makes required d-orbitals empty/available.
- wherein
For example: CO, CN etc
is a strong field ligand which pairs the all unpaired electrons of
which results no unpaired electron in the
