Linkage Photoisomerization of SO2 Bound to Osmium

In this literature discussion, students are asked to explore the chemistry behind a eta-1 to eta-2 linkage photoisomer of sulfur dioxide bound to pentammine osmium. There are questions that tie to chemical structure and the nature of the two bonding modes of the ligand as well as an examination of the spectroscopic properties of the complex in the solid state. Two of the questions ask students to draw some conclusions based on their knowledge of periodic trends and the sigma donor ability of ligands.

SLiThEr #7: Assessment Using Literature Discussions

This is the seventh SLiThEr () in the series. In this presentation/discussion, Dr. Shirley Lin explains how she used a literature discussion with students to assess their learning and knowledge. This was for a upper-division senior seminar course. In particular, she discusses questions at various levels of Bloom's Taxonomy. She also explains how to use concepts from Chemical Education Research to really dig down and assess student knowledge.

SLiThEr #1: Creating online inorganic chemistry labs

Submitted by Kyle Grice / DePaul University on Tue, 12/29/2020 - 14:29

This is the link to the first SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable), presented by Kyle Grice and Hosted by Chip Nataro. The SLiThEr was recorded and posted on YouTube (see the web resources link). 

This particular roundtable focused on the teaching of a Junior/Senior-level inorganic chemistry laboratory completely online. Kyle presented on what he did in Spring 2020 when he had to pivot quickly to a fully remote modality with only a week or so of planning. 

Molecular Orbital and Bond Polarity

Submitted by W. Stephen McNeil / University of British Columbia Okanagan on Wed, 12/16/2020 - 15:30

In 2009, Flick Coleman at Wellesley whipped up a brilliant little web-based tool that showed how the electronegativity and energy difference of atomic orbitals leads to changes in the resulting molecular orbitals. I've used it every year. But it runs on Flash, Flash is about to die forever (no longer supported as of Jan 2021), and I don't think Flick is going to make us an HTML5 version. (And wow I know I can't do that. Does somebody else know how to do that?)

Jahn-Teller effect, theory and examples

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.

A cobalt hydroformylation catalyst tribute to Malcolm Green

Submitted by Chip Nataro / Lafayette College on Mon, 07/27/2020 - 20:00

In this paper (Llewellyn, Green and Cowley, Dalton Trans. 2006, 4164-4168) the synthesis and characterization of two cobalt compounds with an N-heterocyclic carbene ligand (IMes) are reported. the first, [Co(CO)3(IMes)Me] was prepared by the reaction of [Co(CO)3(PPh3)Me] with IMes. The second compound, [Co(CO)3(IMes)COMe] is formed by the addition of Co to the first.

s-p Mixing and the Order of MOs in Diatomic Molecules

Submitted by Michelle Personick / Wesleyan University on Fri, 06/05/2020 - 20:13

These slides provide an introduction to s-p mixing in diatomic molecular orbital diagrams appropriate for students in a general chemistry course. 

MO diagram for square planar methane guided inquiry

This guided inquiry activity takes students through the process of constructing an MO diagram for square planar methane. LGOs are constructed using a graphical approach. Students are guided through a process that allows them to use their MO diagram to make a claim about chemical properties.

MO diagram for water guided inquiry

This guided inquiry activity takes the students through the whole process of constructing an MO diagram for water in detail. The LGOs are constructed using my graphical approach (linked below) and hybrid orbital formation is discussed. Along the way, students are given hints on what to think about when constructing an MO diagram.
