Webthe ligand field is roughly 2/3 of the octahedral field. The direction of ligand approach in tetrahedral complex does not coincide with the d-orbitals. This reduces the field by a factor of 2/3. Therefore ∆ t is roughly 2/3 x 2/3 = 4/9 of ∆ o As a result, all tetrahedral complexes are high-spin since the CFSE is normally smaller than the ... Web(Crystal field splitting energy also applies to tetrahedral complexes: Δ t.)
