Question

Distinguish between inner orbital octahedral and outer orbital octahedral complex.

Answer 1

Inner orbital octahedral complex	Outer orbital octahedral complex
1. It involves (n-1) d, ns and np orbitals for d2 sp3 hybridization.	1. It involves n d, n s and n p orbitals for sp3 d2 hybrid orbitals.
2. It is also known as low spin complex	2. It is known as high spin complex
3. It is generally diamagnetic in nature due to all paired electrons.	3. It is generally paramagnetic in nature due to presence of unpaired electron.
4. Ligands present in these complexes are strong field.	4. Ligands present in these complexes are weak field.
Ex. [Fe(CN)6]3- ,[Fe(CN)6]4- , [Co(NH3)6 ]3+ etc	Ex.[ FeF6]3-, [CoF6 ]3-, [Fe(H2O)6]3+ etc.
