Crystal Field Treatment of Octahedral Compounds
This page presents exercises in CFT diagrams for transition metal complexes. When the "New Question" button is pressed a description of the complex will be provided with sufficient information for you to distribute the metal in the boxes provided. As you might expect, how the information is entered is critical.
- Since we are only interested in complexes where there are two ways to distribute the electrons, the number of cases shown on this page is limited to d4 to d7.
- Getting the electron count on the metal correct is critical-do that carefully
- Enter the metal electrons from the left to the right at each level. If an orbital has a single electron, enter a "1", if it has two electrons, enter a "2".
- Have all the filled orbitals before the half-filled. In principle, 221 is the same as 212, but the data is much more easily checked if a uniform format is followed.
- Example: a d7 is high spin. This means that all five orbital will be filled as if there were of the same energy. This results is the following:
