SLiThErs - Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable

A collection of all of the IONiC VIPEr SLiThErs (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable). These events are short presentations on a topic followed by a period of discussion between the presenter and live participants. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

Interpreting Tanabe-Sunago diagrams

Submitted by Adam Johnson / Harvey Mudd College on Mon, 03/24/2025 - 17:27
Description

I was lecturing along today, teaching the basics of the theory and how to interpret Tanabe-Sunago diagrams, and I got to my slides where I show them how to calculate ∆o from Co(en)3, and it just fell apart. I had done V(III) as a first example, and then I wanted the students to practice the calculations, but my slides were not up to the task. I thought to myself, in the moment, this would be a good opportunity to do an in-class activity, I should write it. So, in the spirit of making next year easier, I did. I have not used this in class, but I wish I had had it this morning. 

Scandium Carbonyls - mysterious myth or legendary legend?

Submitted by James F. Dunne / Central College on Thu, 03/06/2025 - 14:36
Description

This literature discussion is based on a short JACS communication reporting the first isolable Sc(II) carbonyls (not a typo) and isocyanides.  The paper discusses some standard synthesis and characterization while exploring a more fundamental question regarding why Sc, a d-block metal, is considered a rare-earth and when it stops reacting analogously to the rare-earth metals.  The LO focuses on ye olde carbonyl stretching frequencies and back-bonding and makes a nice follow up to an introduction to that concept.  It tries to make students explicitly connect electron configuration to changes

Adducts of XeO3
Description

This literature discussion was prepared as part of the 2025 ACS awards collection in honor of Gary J. Schrobilgen, winner of the M. Frederick Hawthorne Award in Main Group Inorganic Chemistry.

AsF5 - a superacid for super review!

Submitted by James F. Dunne / Central College on Fri, 02/21/2025 - 13:02
Description

This LO was developed as a review activity for the end of the semester.  Students are required to touch on a wide range of topics including acid-base theories, crystal systems, point groups, the spectrochemical series, and 19F NMR spectroscopy.  A close reading of the paper is required helping to build student comprehension of the literature.

Flipping Cobalt Spin States
Description

This activity was designed to assess student comprehension of how changes in pi-donation from ligands can affect both crystal field splitting and metal spin states.  The activity requires students to practice electron counting, idealized crystal field splitting, and then apply these concepts to explain the observed change from low to high spin caused by the loss of a proton.

Moleculuar Computation and Visualization in Undergraduate Education (MoleCVUE)
Description

The MoleCVUE website contains several items that should be of interest to the VIPEr community, especially the activities.  Each activity is designed to be ready to deploy in lecture, laboratory, or as homework.  There are activities covering all of the major subdisciplines of chemistry (some more than others).  Some activities that might be of particular interest to VIPEr are "Group Theory", "VSEPR", and "Electron Configurations of Atoms and Ions".  All of the activities are written to use WebMO, but could be adapted for other systems.  Most activities are doable with the free or demo versi

Literature Discussion Group Project

Submitted by Wes Farrell / United States Naval Academy on Mon, 08/05/2024 - 14:23
Description

This is a literature-based end of semester project.  After a semester of introducing literature in the form of typical literature discussions, this assignment is given to small groups.  It may be easily amended or added to.  Each group is provided with a paper and accompanying questions that are similar to the literature discussions they have done over the semester.  They then must use these guiding questions to assemble a presentation to the class.  The topics chosen and the guiding questions are designed to provide students with a taste of the many areas of inorganic chemistry that are no

Theoretical Analysis of Fe K-edge XANES on Iron Pentacarbonyl
Description

This article focuses on a theoretical analysis of K-edge X-ray Absorption Near Edge Structure (XANES) of Fe(CO)5 in the D3h and C4v geometries. For the context of a one semester inorganic chemistry / physical inorganic chemistry course, the authors use computational methods and experimental X-ray techniques to generate the XANES spectra of two different geometries of Fe(CO)5. Densities of states are used to show overlap between specific orbitals (Fe p with C p), indicating pi-backbonding.

Orca Computational Chemistry Tutorials (Neese)
Description

Frank Neese was honored with the 2024 ACS Award in Inorganic Chemistry for outstanding accomplishments in combining high-level theory with experiment to obtain insight into the properties and reactivities of transition-metal complexes and metalloenzymes. 

His major contributions to the field have been through the development and dissemination of his free computational modeling software program ORCA, which is used by thousands of researchers across the fields of inorganic and bioinorganic chemistry.
