1. Colors and Spectroscopy of Transition Metal Complexes

2. Why is:
Mn2+(aq) colorless
Cu2+(aq) less deeply blue colored than Cu(NH3)42+
Zn2+(aq) colorless
MnO4- deeply colored
W(CO)6 colorless

3. Spectrochemical Series:
Sigma Interaction Strength
Spectrochemical Series:
I- < Br - < Cl- , F- < OH- < OH2 < NH3 < en < CN- < CO

4. Pi Donor Ligands: Mainly oxides and halides

5. Mn2+(aq) MnO4 -

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
