For the inverse spinel structure of Fe3O4 it is easy since the Fe(III) ion has no preference by virtue of it being d5 high spin - so no LFSE in any configuration - we can check this out for the two possibilities: Octahedral, LFSE = 3 x 4Dq for the stabilising t2g orbitals and 2 x 6 Dq for the destabilising eg. orbitals = (12-12) Dq = 0 and for. Spin states when describing transition metal coordination complexes refers to the potential spin configurations of the central metal's d electrons. In many these spin states vary between high-spin and low-spin configurations. These configurations can be understood through the two major models used to describe coordination complexes; crystal.

Respectively. Co(III) d6 ion is low spin because (a) high charge (even with weak ligands like oxo) and (b) maximum gain in CFSE. So the Co 3 O 4 structure is normal spinel. Spinel by definition, the 3+ ion has to go to the O h site leaving the 2+ ion in T d. Fe 3 O 4 is composed of Fe(II) Td and Fe(III) Oh ions with d6 and d5 configurations.

Factors affecting the CFSEFactors affecting the CFSE First, note that the pairing energies for first-row transition metals are relatively constant. Therefore, the difference between strong- and weak-field, or low and high- spin cases comes down to the magnitude of the crystal field splitting energy (Δ). 1. Geometry is one factor, Δ o is large.

Solution The splitting pattern and electron configuration for both isotropic and octahedral ligand fields are compared below. eg +0.GA. -0.4A. 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.

The crystal field stabilization energies (CFSE) of high spin and low spin d 6 metal complexes in terms of ∆ 0, respectively, are- (A) -0.4 and -2.4 (B) -2.4 and -0.4. Solution. The correct option is A -0.6Δ oct. As we know high spin is due to a weak ligand , hence pairing up of electrons does not take place. The following figure shows the filling of electrons in the subshells. oct = 1×(3/5)−[3×(2/5)] oct = −0.6 oct. Chemistry. Assertion In high spin situation, configuration of d 5 ions will be t 2 g 3, e g 2. Reason In high spin situation, pairing energy is less than crystal field energy.

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.
