1. Colors and Spectroscopy of Transition Metal Complexes

2. Why is: 1.Mn 2+ (aq) colorless 2.Cu 2+ (aq) less deeply blue colored than Cu(NH 3 ) 4 2+ 3.Zn 2+ (aq) colorless 4.MnO 4 - deeply colored 5.W(CO) 6 colorless

3. Sigma Interaction Strength Spectrochemical Series: I - < Br - < Cl -, F - < OH - < OH 2 < NH 3 < en < CN - < CO

4. Pi Donor Ligands: Mainly oxides and halides

5. Mn 2+ (aq) MnO 4 -

6. Pi Acceptor Ligands: CO, CN -, pyridine

7. Pi Acceptor Ligands and spectroscopy: CO, CN -, pyridine

8. Reactivity of Transition Metal Complexes Substitution Reactions Redox Reactions Photochemically-Induced Reactions

9. Substitution Reactions: why would they occur?

10. Catalysis Homogeneous vs. Heterogeneous Transition metal complex catalysis
