WebWe're learning about the Crystal Field Theory (CFT, under coordination chemistry) at school now, and my teacher mentioned that the 5 d-orbitals split into orbital sets, namely the $\mathrm{t_{2g}}$ (triply degenerate-gerade) and the $\mathrm{e_{g}}$ (evenly degenerate-gerade) for an octahedral ligand field; whereas for the tetrahedral ligand field, the … WebDec 22, 2014 · To summarise: Adoption of a square planar geometry is favoured due to occupation of four low-energy orbitals formed. Adoption of a tetrahedral geometry is favoured due to (a) relief of steric repulsions; and (b) the relief of electron-electron repulsions due to adoption of a high-spin configuration. When the ligand is C N X −, a …

Why are low spin tetrahedral complexes so rare?

WebCrystal field theory is based on the assumption that the interaction between the metal ions and the ligands is purely electrostatic in nature.

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 ...
