Inorganic Chemistry

Submitted by Dean Johnston / Otterbein University on Mon, 04/26/2021 - 17:41

This course will emphasize the fundamental concepts needed to understand the diverse chemistry of all the elements of the periodic table. The common theme for the entire course will be Structure and Bonding. The primary focus will be inorganic molecules, ions and solids, but the concepts we will discuss are applicable to all aspects of chemistry. The first two-thirds of the course will cover theories of bonding in molecules and solids along with some background in symmetry and structure.

SLiThEr #17: Demonstration of a Transition to a Remote General Chemistry Course

Submitted by Chip Nataro / Lafayette College on Mon, 04/19/2021 - 12:22

Professors Kari Stone and Dan Kissel fro Lewis University describe the transition to a remote general chemistry course through a flipped curriculum using mastery-based grading. In particular, the development and implementation of a element project is discussed as part of the 17th SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable) on 3/4/2021

nanoCHAts: Informal conversations about teaching

Submitted by Hilary Eppley / DePauw University on Wed, 04/07/2021 - 14:33

A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

The Organometallic Chemistry Behind the Polymer of Squares (Chirik)

The discussion covers a 2021 publication by the Chirik group (Nature Chemistry, 2021, DOI: 10.1038/s41557-020-00614-w) which details the discovery of a new way to polymerize butadiene through iron-catalyzed [2+2] cycloadd

Resolution of Werner complexes -- the COVID edition

Submitted by Adam Johnson / Harvey Mudd College on Fri, 02/05/2021 - 12:44

This is a classic experiment that has been revised and updated numerous times over the years. The experiment can be found in Girolami, Rauchfuss and Angelici, 3rd edition, but that edition removed some purification steps that were present in the earlier edition which has plagued generations of my students with poor resolution of the enantiomers. Marion Cass published a J. Chem. Educ. article in 2015 that included a pH determination and added back in the recrystallization step. This allowed my students to achieve higher yields and greater resolution in Spring 2020.

Comparing Homonuclear and Heteronuclear Diatomic Molecules with WebMO

Submitted by Catherine / East Tennessee State University on Wed, 11/04/2020 - 13:07

Students first learn the basics of WebMO by building and optimizing 2 small molecules. They then calculate and visualize the molecular orbitals of two diatomic molecules (N2 and BF) and observe how going from a homonuclear to heteronuclear molecule changes the shape of different molecular orbitals. 

As written this activity uses the WebMO demo server so no computational chemistry software/licences are required.

First Look at Coordination Complexes

Submitted by Anthony L. Fernandez / Merrimack College on Sun, 09/06/2020 - 15:08

When transitioning into inorganic chemistry from organic chemistry, students are surprised by the complexity of metal complexes. To ease this transition, students are asked to look at the crystal structure of a coordination complex [(+/-)cis-dichloro-bis(ethylenediamine)-cobalt(III) chloride monohydrate], make some observations about what they see, and provide a list of questions that they would like answered. Students usually note that there are atoms/ions that are "floating" and are seemingly unattached to anything else in the structure.

Jahn-Teller effect, theory and examples

Submitted by Adam Johnson / Harvey Mudd College on Thu, 08/06/2020 - 18:44

At a recent SLiThEr workshop, a request was put out for an introduction to the Jahn-Teller effect. I had already prepared several slides showcasing single crystal X-ray data for my class this spring so I put this together with some additional examples from my lab and the literature.  Single crystal XRD data is presented to support the claims.

Ferrocene acylation - The Covid-19 Version

Submitted by Chip Nataro / Lafayette College on Sat, 03/21/2020 - 12:56

This is the classic Chromatography of Ferrocene Derivatives experiment from "Synthesis and Technique in Inorganic Chemistry" 3rd Ed. (1986 pp 157-168) by R. J. Angelici.
