Question

What are Inner and Outer Orbital Complexes??

Answer 1

The complexes formed, if have inner d orbitals are called low spin complexes or inner orbital complexes and if having outer d orbitals are called high spin or outer orbital complex. The inner d orbitals are diamagnetic or less paramagnetic in nature hence, they are called low spin complexes.

Answer 2

$\huge\mathfrak\green{Answer :}$


$\huge\textbf{Inner Orbital Complex :}$

→ Inner Orbital Complex that uses inner d - orbital in hybridization... These are also known as Lower Spin Complex.

→ In this d - orbital used in the hybridization are in a lower energy level than s and p orbitals.

→ It's hybridization is d²sp³.

→ Examples :-

$[Fe(CN)_{6}]^{3-}$ and $[Co(NH_{3})_{6}]^{3+}$

$\huge\textbf{Outer Orbital Complexes :}$

→ Outer Orbital Complex that uses outer d - orbital in hybridization... These are also known as Higher Spin Complex.

→ In this d - orbital used in the hybridization are in a same energy level as that of s and p orbitals.

→ It's hybridization is sp³d³.

→ Examples :-

$[CoF_{3}]^{3}$ and $[CO_{6}]^{3-}$
