Cft tetrahedral

WebThe 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 paring energy. Hence low spin configurations are rarely ... WebThe crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in case of …
