Crystal Field Theory

This chemistry video tutorial provides a basic introduction into crystal field theory. It explains how to draw the crystal field splitting diagram of transition metal complex ions using weak field ligands and strong field ligands. It explains the difference between high spin and low spin diagrams and how to determine the magnetic properties of complex ions.

I wanted to ask you, wether you´d like to do a video conference with my school and explain us hwo we can learn chemistry easily and show us your methods. you are very inspirational. The chemistry department would appreciate it.

    Tell me if i'm wrong, but shouldn't the PE in the final exercise be equal to zero. This because you only add P for electrons that pair due to the pairings energy being smaller than going into the eg levels and therefore you add it, otherwise you should have added the +3/5 delta oct. Therefore with high spin, there is never PE involved and for low spin for PE, you only count the pairs that are formed that would not have formed if it had been a low spin complex.

    This is exactly what i wanted to point out. As you say, you only count the pairing that ocurrs in comparison with the hypothetical situation of espherical charge surrounding the metal, when all d orbitals are degenerate. That is because the crystal field stabilization energy is the relative stabilization of the complex vs. the ideal situation where no splitting of the orbitals takes place. This means that, for a d6 in an espherical charge distribution situation you already have one electron paired, so the crystal field stabilization energy for a high spin complex doesnt involve electron pairing.

    The pairing energy contributions to the CFSE are done incorrectly here. The CFSE is the stabilization energy of the d electrons due to the energy splitting of the d orbitals. So, for both the high-spin and low-spin (weak- and strong-field) cases, the comparison should be with a system with zero splitting of the d-orbitals. For a zero-splitting case, there would still be one orbital with two electrons when there is a total of 6 d electrons. Therefore, the CFSE for the d^6 high-spin system does NOT include any pairing energy contribution because that electron pair would still be paired even if the d orbitals weren’t split at all. And the low-spin case would include only 2P, not 3P - again, because one electron pair would still be paired even if the d orbitals weren’t split at all.
