Figure 5.

Ligand-field splitting in some common geometries, compared to the C_3v symmetry of pseudotetrahedral complexes of tripodal ligands,²⁵ and the C_2v symmetry of trigonal-planar β-diketiminate complexes. In each complex, the z axis is vertical on the page; note that the change in orientation causes the orbital labels for β-diketiminate complexes to be different than in Figures 3 and 6. The bold red labels highlight the two d orbitals that have the correct symmetry for π-interactions with the ligand labeled X.
