For [Co(NH3)6]3+, Co3+ (27-3=24) has the configuration 3d6. What is the hybridization and magnetic property?

1. sp3d2 (outer octahedral complex & paramagnetic)
2. d2sp3 (inner octahedral complex & diamagnetic)
3. sp3 (tetrahedral complex & paramagnetic)
4. sp3d (outer octahedral complex & diamagnetic)

Correct answer: d2sp3 (inner octahedral complex & diamagnetic)

Solution

In [Co(NH3)6]3+, Co3+ has a 3d6 configuration. NH3 is a strong field ligand, causing pairing of electrons in the 3d orbitals. This results in a low-spin, inner d2sp3 hybridization and diamagnetic behavior.
