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.
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.
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.
When I saw this paper come out, I thought it would make a great teaching paper. It has synthesis, characterization, reaction mechanisms, computational chemistry and it directly impacts catalysis by a thorough examination of the reductive elimination reaction. What are the factors governing the rate of C-C RE? Can geometry (sterics) control reactivity or is it only based on the hybridization (sp2/sp3) of the carbon atom in question (electronics)?
I wanted my organometallic class to explore the bonding and spectroscopy of the Kubas dihydrogen complex without having to spend the time doing the entire literature discussion (which is really great and I have done it many times in the past) because I wanted to do it in only about 20-30 minutes in a 75 minute class period. Most of the questions come from the Kubas literature discussion, which I shortened. The IR and reduced mass calculations come from an LO I wrote about arene activation by Jones and Feher.
This literature discussion on the Hot Paper communication in Chemistry, A European Journal; highlights the first examples of borepinium and borfluorenium cations whose optical properties can be tuned and also the very first reported example of thermochromism in these cationic species.

Chip Nataro (Lafayette College) hosts a live discussion covering the favorite labs that people teach. The discussion somewhat evolved into a conversation on "so, you are teaching inorganic lab for the first time...what do you do?"
Descriptive chemistry of the main group elements with some emphasis on the non-metals. Transition metal compounds: aspects of bonding, spectra, and reactivity; complexes of n-acceptor ligands; organometallic compounds and their role in catalysis; metals in biological systems; preparative, analytical, and instrumental techniques.
This LO uses borane and carborane clusters to practice assigning point groups and counting electrons. It also asks students to recall electronegativity trends to predict dipoles, and they can check their predictions against calculated Mulliken charges.
The second 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.
