Coordination Compounds

Question

Wired Faculty App

In octahedral complexes which two d-orbitals are used in hybridization.

Solution

Octahedral geometry arises due to d2sp3 or sp3d2 hybridisation of the central metal atom or ion. Octahedral complexes in which the central atom is d2sp3 hybridised are called inner- orbital octahedral complexes while the octahedral complexes in which the central atom is sp3d2 hybridised are called outer orbital octahedral.
