During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.
The guided reading questions may be graded using the answer key.
These questions have not yet been assigned to students.
Guided reading and in-class discussion questions for "High-Spin Square-Planar Co(II) and Fe(II) Complexes and Reasons for Their Electronic Structure."
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.
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.
A portion of their grade (20%) is dedicated to literature discussions (4-6 over the course of the semester). The grading rubric involves 3 possible ratings for each question/answer: “excellent”, “acceptable”, or “needs work”.
Concepts covered during literature discussions will be included among exam materials.
This Guided Literature Discussion was assigned as a course project, and is the result of work originated by students Christopher Lasterand Patrick Wilson. It is based on the article “Deca-Arylsamarocene: An Unusually Inert Sm(II) Sandwich Complex” by Niels J. C. van Velzen and Sjoerd Harder in Organometallics 2018, 37, 2263−2271. It includes a Reading Guide that will direct students to specific sections of the paper that were emphasized in the discussion. This article presents a study of the reactivity of bulky CpAr-Et/iPr2 Sm complexes that is contrasted to the more well-known Cp*2Sm.
After reading and discussing this article, a student should be able to…
- Be more familiar with the chemistry of sandwich samarocene complexes.
- Understand how bulky ligands affect structure and reactivity in a sandwich complex.
- Apply the CBC method to identify ligand functions and metal valence number/ligand bond number.
- Understand how XRD bond distances can help determine a ligand charge.
I am planning on assigning this LO as a graded in-class group discussion. Students will be given a copy of the article, reading guide, and discussion questions one week in advance. On the day of the discussion, students will be assigned in groups of 2-3. They will then have one lecture period to answer the questions in writing as a group.
