ligand pi system irreducible representation for trigonal bipyramidal transition metal complex
I am considering a D$_{3h}$ trigonal bipyramidal transition metal complex MX$_5$. I have found that the irreducible representation for the ligand s and $\sigma$ systems is 2A$_1'$+A$_2''$+E$'$. I ...

Derivation of the Orgel diagram for octahedral d2 complexes
The Orgel diagram for a typical octahedral $\mathrm{d^2}$ complex is shown below:
(source: Kettle, Physical Inorganic Chemistry, p 146)
I understand that the right-hand half of the graph shows how ...

How do I find the ground state term symbol for transition metal complexes?
I have a problem where I'm trying to match metal complexes with the proper ground state term symbol. I've tried doing a Google search and looking for a process, but haven't had any luck. I decided ...

How do I determine the number and order of ligand orbitals?
I am trying to create interaction diagrams for transition metal species by reducing the representations for both $\sigma$ and $\pi$ ligand orbital sets and mixing them with the metal orbitals. The ...

Orbital mixing in square planar D4h complexes
Consider a square planar $\ce{ML4}$ complex with $D_\mathrm{4h}$ symmetry. Which orbital should the $\mathrm{a_{1g}}$ SALC of the ligands mix with, $\mathrm{3d}_{z^2}$ or $\mathrm{4s}$? Both of those ...

How do I determine the crystal field splitting for an arbitrary point group?
How can I figure out the degeneracy of the d orbitals for a site that has a given point group? Specifically I'm interested in $D_{3d}$ and $D_{3h}$, but it would be good to know how to do it in the ...
