In Exam 2 we covered the frontier orbitals of the B-diketiminate (NacNac) ligand. A student in Tom's group is using these NacNac ligands to make heteroleptic Cu(phenanthroline) (NacNac) complexes, shown below. Note that the frontier orbitals in these compounds are all ligand orbitals, shown from the top view with only the top lobe each pr orbital indicated. Ph. .Ph Ph- Cu LUMO b₂ .Ph Ph Cu LUMO+1 a₂ Cu .Ph HOMO b₂ Ph These complexes are d10 with closed-shell ground states. On exam 2 we determined that the HOMO has b2 symmetry. The LUMO and the LUMO+1 have b2 and a2 symmetry, respectively. Give the term-symbols for the following: (2 points each) Spin-allowed HOMO-LUMO excited state: Spin-allowed HOMO-LUMO+1 excited state: The lowest-energy triplet state in the above complex is predicted to be 3A₁. Use spin-orbit coupling to determine the representations (Mulliken symbols) for the three triplet sublevels. Enter the Mulliken symbols in the order they appear on the C2y character table.
