This collection of learning objects was created to celebrate the National ACS Award Winners 2022 who are members of the Division of Inorganic Chemistry. The list of award winners is shown below. 

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.

Literature discussion for “Synthesis and characterization of a formal 21-electron cobaltocene derivative.”

Submitted by Wes Farrell / United States Naval Academy on Wed, 05/15/2024 - 14:34
Description

This is a literature discussion regarding electron counting.  It involves several opportunities for students to use CBC to determine electron counts themselves.  Then, it demonstrates the first case of a 21-electron complex, which leads to great discussion regarding the 18-electron rule.  Throughout the discussion, students are introduced to many structural and spectrochemical analyses, some of which may be new to them.

Theoretical Analysis of Fe K-edge XANES on Iron Pentacarbonyl

Submitted by Prajay Patel / University of Dallas on Tue, 04/30/2024 - 15:01
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.

The elusive tetrabenzylthorium compound (Bart)
Description

This literature discussion learning object describes the isolation and structure of tetrabenzylthorium, a molecule that was synthesized many years ago but was never thoroughly characterized.

SLiThEr #57: What to do when your published results are questioned?

Submitted by Kyle Grice / DePaul University on Tue, 02/13/2024 - 15:19
Description

This was the 57th SLiThEr, presented by Dr. George Stanley, retired professor from LSU. It was a very interesting story and would be a valuable lesson to students about proper characterization and working with challenging and paramagnetic systems. 

Iridium dihydroxybipyridine complexes for hydrodeoxygenation

Submitted by Adam Johnson / Harvey Mudd College on Thu, 01/04/2024 - 17:50
Description

I regularly give an oral exam instead of a written exam in my junior and senior level organometallics seminar course. The course focuses on the primary literature, discussion of advanced topics, and asking questions. A written exam would not evaluate the students' abilities on the important skill development they learned in the class. Besides, I am better able to gauge when a student has no idea about a certain topic, or just needs a little nudge in order for them to demonstrate that they actually understand 95% of it.

Synthesis of Ti complexes supported by an ortho-terphenoxide

Submitted by Adam Johnson / Harvey Mudd College on Thu, 01/04/2024 - 16:21
Description

The Tonks group has helped to revitalize interest in early metal, especially titanium, organometallic chemistry in recent years. Often his group uses Ti complexes for multi-component coupling, increasingly with masked low-valent Ti(II) as an important intermediate. This paper is more fundamental, exploring a ligand based on ortho-terphenoxide since the meta- and para- derivatives were already known. Along the way, they report some interesting NMR and structural information, and finish with some hydroamination catalysis. 

Geometric Control of C-C RE from a Pt(IV) Pincer Complex

Submitted by Adam Johnson / Harvey Mudd College on Thu, 01/04/2024 - 15:10
Description

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)?
