Coordination entities with only three ligand groups attached

coordination-entities-with-only-three-ligand-groups-attached

Coordination entities with only three ligand groups attached to the metal ion can have d^2sp^3 hybridisation.

A. True

B. False

I had been asked this question in class test.

My question is from Bonding in Coordination Compounds in section Coordination Compounds of Chemistry – Class 12

The correct choice is A. True

The best explanation: This happens in the case of didentate ligands which have six pairs of electrons from three molecules. For example, [Co(ox)3]^3- has d^2sp^3 hybridisation and is diamagnetic.
