The Structure and Color of Alums

Submitted by EGunn / Simmons College on Mon, 07/14/2014 - 13:09
Description

This is an in-class assignment designed to help students integrate their understanding of periodic trends and materials properties. Using the color of alum crystals as an example of octahedral coordination chemistry, students use their knowledge of electronic structure and periodic trends to predict which of the isomorphous alum crystals will be colored, and to qualtitatively rank the degree of crystal field splitting in a family of alum crystals.

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.

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.

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.

Five Slides About Concurrent Tandem Catalysis

Submitted by Shirley Lin / United States Naval Academy on Thu, 07/03/2014 - 12:54
Description

This set of slides is adapted from a presentation given at the ACS National Meeting in New Orleans Spring 2013 in the symposium "Undergraduate Research at the Frontiers of Inorganic Chemistry" organized by members of the VIPEr leadership council. The slides are from the introduction to the presentation that takes the audience through how catalytic cycles are depicted and then to the concept of concurrent tandem catalysis (CTC). At the end, there is a slide with references that gives an example of how CTC can be applied to aryl halide substrates to form new C-C and C-H bonds.

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.

Learning Objects used at the 2014 VIPEr Workshop on Bioinorganic Chemistry

Submitted by Betsy Jamieson / Smith College on Wed, 06/25/2014 - 09:32

This collection highlights the learning objects used at the 2014 VIPEr workshop on the Bioinorganic Applications of Coordination Chemistry to introduce participants to the field of bioinorganic chemistry.   They provide essential background information on how metals bind to proteins as well as the techniques used in the research papers presented at the workshop.  A list of learning objects created at the workshop based on the current research of our expert speakers can be found at: 

Properties of olefin complexes: Pt(II) vs Au(III)

Submitted by Margaret Scheuermann / Western Washington University on Sat, 06/21/2014 - 22:01
Description

This is a literature discussion based on a paper titled “Generation and Structural Characterization of a Gold(III) Alkene Complex” (Angew. Chem. Int. Ed. 2013, 52, 1660 - DOI 10.1002/anie.201209140) that reports the first crystallographically characterized Au(III) alkene complex, [(cod)AuMe2] [BArF]. The synthesis and characterization of [(cod)AuMe2] [BArF] are presented. The structural properties are compared to those of the isoelectronic species (cod)PtMe2, and to free cod.

Complexes of alkenes, alkynes, and dienes

Submitted by Margaret Scheuermann / Western Washington University on Sat, 06/21/2014 - 21:35
Description

These slides provide an outline of the significance, bonding, properties, and reactivity of metal alkene, alkyne, and diene complexes appropriate for an upper division organometallics class. Animation is used to construct qualitative MO diagrams for olefins bound to octahedral metal centers that highlight specific bonding and antibonding interactions.

The chemdraw file used to create these slides is also provided.

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
