Submitted by Shirley Lin / United States Naval Academy on Sat, 03/12/2022 - 07:01

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. 

Metallocene cations and anions

Submitted by Chip Nataro / Lafayette College on Tue, 09/23/2025 - 11:39
Description

This is a really interesting paper in J. Am. Chem. Soc. (2025, 147, 34641-34646) involving a complex salt in which both the cation and anion are metallocenes. While a majority of the paper is focused on the characterization of two new compounds, it presents some excellent opportunities to practice counting electrons, one of which was a challenge to this author.

Rhenium isocyanide complexes from the Figueroa group

Submitted by Chip Nataro / Lafayette College on Tue, 08/26/2025 - 13:34
Description

This literature discussion is in honor of Dr. Josh Figueroa, recipient of the 2026 F. Albert Cotton Award in Synthetic Inorganic Chemistry. Josh has done some tremendous work with isocyanide ligands and this paper is but a brief glimpse into this field. The complexes of interest contain carbonyl ligands and isocyanide ligands, so there are plenty of opportunities for students to use group theory to predict the number of IR-active vibrations for these ligands.

Hydrocyanation

Submitted by Chip Nataro / Lafayette College on Mon, 07/07/2025 - 07:35
Description

This literature discussion was inspired by a talk given by Dr. Nora Radu, recipient of the 2025 ACS Award for Distinguished Service in the Advancement of Inorganic Chemistry. It is a bit 'big picture' in nature in that the hydrocyanation reaction is important for the synthesis of nylon. As such, there is a significant amount of background material relating to nylon-6,6. Students will read an article from C&EN, portions of a patent, and portions of an article from J. Chem.

COMFORT, A web resource for fragment molecular orbitals of simple fragments

Submitted by samuelson / Indian Institute of Science on Tue, 06/17/2025 - 02:56
Description

The website entitled COMFORT (https://ipc.iisc.ac.in/~ags/ip312/comfort.html) is a easy way to visualise fragment molecular orbitals of many different organic ligands and also metal fragments. One can match the frontier orbitals of the fragments to see if they can form stable molecules. It helps one to see how fragments of an octahedral organometallic complex can be stripped of its ligands one by one to generate fragments that can match organic ligands with multiple "pi" bonds.

Determining Oxidation State: The Arrow Pushing Method

Submitted by Jared Pienkos / University of Tennessee at Chattanooga on Mon, 04/14/2025 - 10:05
Description
    1. Determining the oxidation state of atoms is foundational in chemistry. For inorganic chemistry, students must be able to accurately calculate oxidation numbers of transition metals, which can differ depending on the ligands attached.

Coordination Bonding with Main Group Metals(?)

Submitted by A. M. Christianson / Bellarmine University on Wed, 12/11/2024 - 10:19
Description

This Literature Discussion considers the synthesis of the first carbene-bismuthinidene complex by Gilliard and coworkers in 2019. This molecule serves as an illustration of different bonding models, as it can be described by multiple resonance structures invoking fully covalent, zwitterionic, and coordinate/dative bonding forms. Students analyze these resonance structures and their geometrical implications, then compare to the experimental structural evidence to come to a conclusion about which bonding model(s) best describe this molecule!
