Comparison of CFT (ionic at left) and LFT (molecular orbital at right) development of the d-orbital splitting diagram for octahedral systems. Both reduce to the equivalent consideration of insertion and location of metal d electrons in two degenerate sets of orbitals separated by a relatively small energy...

SAMPLE PROBLEM 22.5 Identifying Complex Ions as High Spin or Low Spin Problem Iron(II) forms an essential complex in hemoglobin. For each of the two octahedral complex ions [Fe(H20)6]"" and [Fe(CN)6]" , draw an orbital splitting diagram, predict the number of unpaired electrons, and identify the ion as low spin or high spin. 

Octahedral Complexes. We shall first apply an argument of the type outlined above to octahedral complexes, using the -orbital-splitting diagram previously deduced from CFT. As indicated in Fig. 20-10, we may place one, two and three electrons in the d orbitals without any possible uncertainty about how they will occupy the orbitals. They will naturally enter the more stable t2g orbitals with their spins all parallel, and this will be true... 

Tbp. From the orbital splitting diagram, Fig. 20-8, where <5X is small, comparable to A( values, while <52 is larger, comparable to A0 values, we can make the following inferences ... 

Why is Co(NH3)e diamagnetic whereas CoFe is paramagnetic Some octahedral complex ions have the same r/-orbital splitting diagrams whether they are high-spin or low-spin. For which of the following is this true ...
