Synthesizing and Investigating Cobalt Complexes: UV-Vis and Structure-Property Relationships

Post-Lab Activity

Therefore, the more π-accepting capability of a ligand, the larger the Δ; the more π-donating capability of a ligand, the smaller the Δ.

The way electrons occupy d-orbitals that are split is affected by the magnitude of the split/difference between the sets of orbitals (Δ). Image A represents the d-orbitals of a π-donating ligand/metal complex. Image B represents a π-accepting ligand/metal complex.

12. Describe, in your own words, how Δ affects how electrons occupy d-orbitals.
