Crystal Field Stabilisation Energy (CFSE) A consequence of Crystal Field Theory is that the distribution of electrons in the d orbitals can lead to stabilisation for some electron configurations. It is a simple matter to calculate this stabilisation since all that is needed is the electron configuration. For an octahedral complex, an electron in the more stable t 2g subset is. Generalisations: • Both the high spin and low spin complexes of d0,d1,d2,d7,d9,d10 and high spin complexes of d4,d5,d6 are generally labile. • Both high spin and low spin complexes of d3,d8 and low spin complexes of d4,d5,d6 are generally inert. 18. Limitations of CFT interpretation. 19. INTERESTING MECHANISM 20. The associative pathway. High spin metal complexes with d4, d5, d6, d7 are also labile in nature and react quickly through the associative pathway. Low spin complexes of d7 metal ions are also found to be labile due to CFSE gain. It can be seen that d4 low spin are also labile in nature.

For d n cases that could be high- or low-spin, the configuration that results in the lower CFSE for the Δo of the complex is the spin state that is observed. • For the hypothetical case Δo = P, neither state would be preferred, as the two CFSEs for d 7 illustrate: CFSE(d 7 low) = -1.8Δ o + 3P = -1.8Δo + 3Δo = 1.2Δo CFSE(d 7 high. The energy separation between these two sets is known as CFSE crystal field splitting energy, denoted by Δ 0. Explanation: Whether a complex will be high spin or low spin, is determined by the magnitude of CFSE. The energy of the ' t 2g ' orbitals is lowered by.4 Δ 0 and the energy of 'e g ' is raised by.6 Δ 0 each. The low-spin (top) example has five electrons in the t 2g orbitals, so the total CFSE is 5 x 2 / 5 Δ oct = 2Δ oct. In the high-spin (lower) example, the CFSE is (3 x 2 / 5 Δ oct ) - (2 x 3 / 5 Δ oct ) = 0 - in this case, the stabilization generated by the electrons in the lower orbitals is canceled out by the destabilizing effect of the.

The possibility of high and low spin complexes exists for configurations d 5-d 7 as well. The following general trends can be used to predict whether a complex will be high or low spin. For 3d metals (d 4-d 7): In general, low spin complexes occur with very strong ligands, such as cyanide. High spin complexes are common with ligands which are. In the case of high spin complex Δo is small. Thus, the energy required to pair up the fourth electron with the electrons of lower energy d- orbitals would be higher than that required to place the electrons in the higher d -orbital. Thus pairing does not occur.For high spin d4 octahedral complex,therefore, Crystal field stabilisation energy= (-3 x 0.4 +1 x 0.6) Δo= - (-1.2 x 0.6 )Δo=-0.6 Δo.

Crystal field stabilisation energy for high spin d4 octahedral complex.

CFSE = Eligand field − Eisotropic field = ( − 4 / 5Δo + 2P) − 2P = − 4 / 5Δo. Notice that the Spin pairing Energy falls out in this case (and will when calculating the CFSE of high spin complexes) since the number of paired electrons in the ligand field is the same as that in isotropic field of the free metal ion. Let's go back to our comparison between the high-spin and low-spin case. For high spin, that's: o o = -0.6Δ o-1 = -9,600 cm-1. For the low-spin case, that's. o = -1.6Δ o-1 = -25,600 cm-1. That means that the low-spin case is lower in energy, by 14,000 cm-1. However, we still need to include the pairing energy. Like the field splitting, the.
