SLiThEr #42: Our Favorite Labs

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

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.

Inorganic Chemistry I

Submitted by Rudy Luck / Michigan Technological University on Wed, 08/17/2022 - 15:52

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. 

RSC Transition Metal Games

RSC has a series of chemistry games that can be downloaded from their website. The link here is specifically for games related to transition metals. There are three games (a Jeopardy! style game, a Password-style game and a Taboo-style game).  The game formats could easily be adapted to other content. You may need to sign up for a free instructor account to access the resources.

Relating Ligand Field Theory to Nickel Complex Color

This In-Class Activity is meant to follow up discussions of ligand field theory toward the end of MO theory including the effects of sigma donors, pi donors, and pi acceptors, and how it relates to absorption spectra and observed color of some transition metal complexes. Students have learned crystal field theory and the effects of geometry/symmetry on ∆, then we extend to LFT and how the chemistries of different ligands affect ∆.

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.

Inorganic Chemistry

The wave nature of electrons is applied to atomic structure and periodic trends. Inter and intramolecular bonding models are used to interpret the chemical and physical properties of various materials, from simplistic diatomic molecules to structurally complex molecular and ionic systems.

The ditungsten tetracarboxylate story (Sattelberger)

This literature discussion learning object examines the first reported synthesis in 1983 of the long anticipated quadruply bonded ditungsten tetracarboxylate dimers by Dr. Al Sattelberger and co-workers. This LO is part of a special VIPEr collection honoring the 2022 ACS National Award recipients in the field of inorganic chemistry. Alfred P. Sattelberger was the recipient of the 2022 ACS Award for Distinguished Service in the Advancement of Inorganic Chemistry.
