These questions have not yet been assigned to students.
Description:
Guided reading and in-class discussion questions for "High-Spin Square-Planar Co(II) and Fe(II) Complexes and Reasons for Their Electronic Structure."
Prerequisites:
Corequisites:
Course Level:
Subdiscipline:
Learning Goals:
1. Bring together ligand field theory and symmetry.
Students should be able to identify symmetry of novel molecules in the literature.
Students should be able to explain d-orbital ordering in a coordination complex using ligand field theory.
Students should be able to identify donor/acceptor properties of previously unseen ligands.
Students should be able to apply your knowledge of electronic transitions to the primary literature.
Students should be able to become more familiar with 4-coordinate geometries.
Students should be able to predict magnetic moments of high-spin and low-spin square-planar complexes.
Students should be able to identify properties of ligands that favor formation of the highly unusual high-spin square planar complexes.
2. Students should comfortable with reading and understanding primary literature.

Implementation Notes:
You do not have to assign all of the guided reading questions at once. You may consider assigning questions as they pertain to where you are in your inorganic chemistry class.
Time Required:
this has not been used yet for in-class discussion.

Zinc-Zinc Bonds (Expanded and Updated)
Submitted by Wesley S. Farrell, United States Naval AcademyEvaluation Methods:
Performance and participation in the discussion will be assessed
Evaluation Results:
None collected yet. Evaluation data will be added in the future.
Description:
This paper in Science reports the synthesis of decamethyldizincocene, a stable compound of Zn(I) with a zinc-zinc bond. In the original LO, the title compound and the starting material, bis(pentamethylcyclopentadienyl)zinc, offer a nice link to metallocene chemistry, electron counting, and different modes of binding of cyclopentadienyl rings as well as more advanced discussions of MO diagrams. More fundamental discussion could focus on the question of what constitutes the evidence for a chemical bond, in this case, the existence of a zinc-zinc bond. In this updated LO, these topics are still covered, however additional topics, such as point group idenitifaction, details regarding the reaction mechanism, electronic structure, and searching the literature using SciFinder are covered. Additionally, electron counting is divided into both the covalent and ionic models.

Prerequisites:
Learning Goals:
Students should become more confident reading the primary literature
Students should be able to apply existing knowledge to interpret research results.
Students should be able to apply electron counting formalisms to organometallic compounds.
Students should be able to use 1H NMR spectroscopy data to rationalize structure.
Students can rationalize bond distances based on periodic trends in atomic radii
Students use SciFinder to put this work into a larger context.
Students identify redox reactions based on oxidation changes.
Students identify molecular point groups based upon structures.
Students should be able to connect d electron count to observed colors of compounds.
