The magnitude of crystal field splitting energy (CFSE) in tetrahedral Complexes is quite small and it is always less
than the pairing energy. Due to this reason pairing of electron is energetically
unfavorable. Thus all the tetrahedral Complexes are high spin Complexes. In fact no tetrahedral Complex
with low spin has been found to exist.
