The Synthesis and Characterization of a trans-Dioxorhenium(V) Complex

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Mon, 07/14/2014 - 12:31
Description

This experiment involves the preparation of a key starting reactant in high purity and yield for an ongoing research project, specifically for the development of potential photodynamic therapy (PDT) agents. The students synthesize [ReO2(py)4]Cl.2H2O using standard inorganic synthesis techniques. The students visualize the vibrations and electronic properties (e.g. molecular orbitals) of the compound using output files generated from density functional theory (DFT).

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.

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.
