Under pressure: Structure and bonding in actinide complexes (Arnold)

Submitted by Amy Price / UC Berkeley and Lawrence Berkeley National Laboratory on Fri, 05/26/2023 - 15:24
Description


This literature discussion focuses on a 2022 Nature Comm paper looking at the reasons behind the pyramidal structures of tri-coordinate f-element complexes. There is plenty to discuss in terms of bonding and coordination geometries in metal complexes, and the effects of pressure on coordination geometry.

Building Heteronuclear Diatomic MOs

Submitted by Andrea Van Duzor / Chicago State University on Thu, 01/26/2023 - 14:53
Description

A guided inquiry activity for students to build the MO diagram for HF based on energetic and symmetry considerations.  Students then compare their model to a standard MO diagram and examine what additional information a MO diagram conveys that the Lewis structure does not.

Phosphate Reduction by Mechanochemistry (Cummins)

Submitted by Kyle Grice / DePaul University on Fri, 01/13/2023 - 11:15
Description

This Literature Discussion LO was created for the ACS Inorganic Chemistry Award Winners. Dr. Kit Cummins was the recipient of the 2023 Frederick Hawthorne Award in Main Group Inorganic Chemistry. This LO is based on a recent paper from the group of Dr. Cummins, entitled "Sustainable Production of Reduced Phosphorus Compounds: Mechanochemical Hydride Phosphorylation Using Condensed Phosphates as a Route to Phosphite", published in ACS Central Science20228, 332-339.

SLiThEr #42: Our Favorite Labs

Submitted by Chip Nataro / Lafayette College on Thu, 11/17/2022 - 08:29
Description

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?"

Molecular Magnets with Lanthanide Metal-Metal Bonding

Submitted by A. M. Christianson / Bellarmine University on Wed, 08/24/2022 - 11:36
Description

This literature discussion is based on a 2022 Science paper describing a series of dilanthanide complexes with exceptional magnetic properties due to the presence of metal-metal bonding. These molecules are the first reported species to feature direct bonding between two lanthanides! The paper contains ample material for discussion of molecular symmetry and bonding, oxidation states and electron configurations, and magnetism. The handout includes a description, glossary, discussion questions, and pre-class worksheet.

Fluorine Azide and Fluorine Nitrate: Structure and Bonding

Submitted by Shirley Lin / United States Naval Academy on Mon, 08/08/2022 - 14:23
Description

This literature discussion was written for a foundation-level inorganic chemistry course to accompany the material on Lewis structures. It utilizes a communication-length article on fluorine azide and fluorine nitrate. The assignment is divided into two parts: a set of questions for students to answer BEFORE they read the communication and then a set of questions that they answer after reading the article.

VIPEr Fellows 2022 Workshop Favorites

Submitted by Barbara Reisner / James Madison University on Sun, 06/26/2022 - 14:31

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.

SALC: An Orbital Arrangement Game

Submitted by Madalyn Radlauer / San Jose State University on Wed, 06/15/2022 - 00:13
Description

We have developed a tabletop game to help students get comfortable with symmetry adapted linear combinations of orbitals (SALCs), a conceptual model used to understand bonding in molecular orbital theory. We have found that students often get anxious about SALCs and miss not only the visual connections to symmetry, but also the fun! This LO includes information about the game, files you can use to print your own copy as well as a link in case you want to purchase a copy, and an example of how it might be incorporated into the classroom. 

Metal-Ligand Multiple Bonds: The Discovery of “Double Nickel” (Hillhouse)

Submitted by Anthony L. Fernandez / Merrimack College on Wed, 06/01/2022 - 00:52
Description

This LO focuses on creating complexes with multiple bonds between late transition metals and nitrogen. The questions will guide students through Mindiola and Hillhouse's communication that details the synthesis and investigation of three-coordinate terminal amido and imido complexes of nickel. This communication is significant because it describes the synthesis and structural characterization of what became known as his "double nickel" complex, which contains a Ni-N double bond.
