Question

Low spin configurations are rarely observed in tetrahedral coordination entity formation

Answer 1

Hey buddy,
I assume you want to know the reason why.

# Reason-
- Generally, the energy gap between two levels(Δt) of tetrahedral complexes is less than the pairing energy.
- In these complexes, electrons will move up to the higher energy orbitals rather than pair. Because of this, most tetrahedral complexes are high spin.
- Also sp3 hybridization in tetrahedral complexes promotes retention of unpaired electrons and thus high spins.

Hope this is useful...

Answer 2

Answer:

It is rare for the Δt of tetrahedral complexes to exceed the pairing energy. Usually, electrons will move up to the higher energy orbitals rather than pair. Because of this, most tetrahedral complexes are high spin.
