WebThis 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 paring energy. Hence low spin configurations are rarely observed. Usually, if a very strong field ligand is present, the square planar geometry will be ... WebIn terms of crystal field theory, the larger gap between t2g and energy levels in strong field ligands is essentially a consequence of the raising of the energy levels by electrostatic interactions between the ligand and the d electrons of the metal.
