Inorganic Spectroscopy Introduced Using an Interactive PhET Simulation (Part 2)

Submitted by Alycia Palmer / The Ohio State University on Mon, 07/14/2014 - 09:06
Description

This is the second part of a two-day class discussion on molecular and inorganic spectroscopy. In this activity, upper level students learn about spectroscopic tecniques used in inorganic chemistry and then devise an experiment to follow the progress of a hypothetical reaction. The activity also prepares students for the inorganic laboratory "Linkage isomerism of nitrogen dioxide" in which infrared spectroscopy is used to monitor changes to the N-O vibrational stretch upon coordination to a metal.

Coordination Diversity and Biological Activity of a Monodentate Au(III) Compound

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Thu, 07/10/2014 - 13:21
Description

 

This learning object focuses on a recent publication (Acta Crystallographia 2014, C70, 260 -266) by the Collins research group in the Department of Chemistry at The College of Wooster.  Specifically, the paper evaluates the coordination diversity of a N-donor ligand, 2-phenyl-1,10-phenanthroline(pnp) with three new pnp-metal complexes containing Au(III), Cu(II), and Pd(II) metal centers.

Practical MCD Tutorial- How to collect MCD Data- Lehnert Lab

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 07/10/2014 - 11:32
Description

Nicolai Lehnert's group recently shared this video they made for the Penn State Bioinorganic Workshops on Youtube.  This is a great practical demonstration of how MCD data is actually collected.

5 (or 6) Slides about Biophysical Techniques

Submitted by Sheila Smith / University of Michigan- Dearborn on Wed, 07/09/2014 - 14:58
Description

This Five Slides About was prepared specifically for the 2014 IONiC/VIPEr workshop Bioinorganic Applications of Coordination Chemistry held at Northwestern University July 13-18, 2014.  

Dissecting Catalysts for Artificial Photosynthesis

Submitted by Anne Bentley / Lewis & Clark College on Mon, 07/07/2014 - 13:57
Description

Anne asked the students in her junior/senior inorganic course to develop their own literature discussion learning objects and lead the rest of the class in a discussion of their article.  Each student chose one article from a list of suggestions provided.  Student Hayley Johnston chose this article describing a Mn-containing catalyst for carbon dioxide reduction (Jonathan M. Smieja, Matthew D. Sampson, Kyle A. Grice, Eric E. Benson, Jesse D. Froehlich, and Clifford P.

Hard Soft Acid Base Theory - Coordination Trends in Alkali Metal Crown Ether Uranyl Halide Complexes: The Series [A(Crown)]2[UO2X4] Where A = Li, Na, K, and X = Cl, Br

Submitted by Gerard Rowe / University of South Carolina Aiken on Tue, 07/01/2014 - 11:13
Description

In this literature discussion, students are asked to read an article describing a series of uranyl halide compounds that contain an alkali counterion that interacts with one or more of the uranium's ligand atoms.  This paper stands out as a great example of the binding preferences of acids and bases, and can be explained very well using simple HSAB concepts.

Exploring Proteins as Ligands using the Protein Data Bank

Submitted by Betsy Jamieson / Smith College on Tue, 06/17/2014 - 15:23
Description

This in class activity is designed to introduce students to how amino acid side chains can coordinate metal ions in proteins.  It guides students through the exploration of several metal binding sites in proteins using the Ligand Explorer program on the Protein Data Bank (PDB) website.  Essentially, it is a way for them to use the PDB to “discover” the information generally presented on this topic in the introductory chapters of bioinorganic textbooks.  At the end it asks students to think about Hard Soft Acid Base theory and to see how that can be applied to the binding of metals in protei

Protein Electrochemistry 3rd Bioinorganic Workshop

Submitted by Sheila Smith / University of Michigan- Dearborn on Tue, 06/10/2014 - 15:17
Description

This is a 90 minute talk by Fraser Armstrong of Oxford University (http://armstrong.chem.ox.ac.uk) explaining the electrochemistry of proteins immobilized on surfaces.  The talk was presented at the 3rd Bioinorganic Workshop in 2014 at Pennsylvania State University.  The talk contains an excellent basic tutorial on simple electron transfer on immobilized substrates using simple iron sulfur proteins as the primary example.

A Review of 3DMolSym: A Web Resource for Teaching Molecular Symmetry

Submitted by Marion Cass / Carleton College on Fri, 05/23/2014 - 19:22
Description

Introducing you to 3DMolSym:  A Web Resource for Teaching Molecular Symmetry that uses Adobe Shockwave for Visualizations and Animations.

Note there is a slight difference when operating this resource on a Mac or in a Windows Operating Systerm.  On a Mac if you don't change an item (any item) in the pull down menu on the right when the resouce opens, the selection of molecules will be frame shifted by one molecule.  An easy fix is described in the Description below.

The Structure and Symmetry of Metal Tris Chelates

Submitted by Marion Cass / Carleton College on Fri, 05/23/2014 - 15:59
Description

I have provided a link to a Web Resource:  The Strucutre and Symmetry of Metal Tris Chelates which I developed several years ago with my collegue Henry Rzepa from Imperial College London (and which was posted as Web Ware on the Jourmal of Chemical Education Website and is not longer available to view there).  The Web site uses 3D images of known molecules and scripted commands to teach about the symmetry elements and operations in these molecules.  Instruction is also given on assigning absolute configurations and ligand twist conformations.  Animations of the Bailar Twist and Ray Dutt Mech
