A Redox-Activated MRI Contrast Agent that Switches Between Paramagnetic and Diamagnetic States

Submitted by Vivian / Clemson University, Department of Chemistry on Wed, 07/16/2014 - 22:04
Description

Students are asked to read an article detailing the development of a cobalt-based MRI contrast agent ("A Redox-Activated MRI Contrast Agent that Switches Between Paramagnetic and Diamagnetic States", Tsitovich, P. B.; Spernyak, J. A.;  Morrow, J. R. Angew. Chem. Int. Ed. 201352, 14247-14250,  DOI: 10.1002/anie.201306394). Before coming to class the students are asked to answer a series of questions designed to guide them through the first half of the article, and to be prepared to discuss their answers in class.

Application of binomial distribution to interpret 31P NMR for aqueous solution of alpha-dodecatungstophosphoric acid, H3[PW12O40]

Submitted by Poloxymetman / Canisius College on Mon, 07/14/2014 - 17:44
Description

31-P NMR spectrum of alpha-dodecatungstophosphoric acid is a combination of thirteen spectra, each spectrum representing the compound with a different number of 183W isotopes per molecule. In order to fully interpret the spectrum one needs to apply binomial distribution to calculate the mole fractions of the molecules with various numbers of 183W isotopes.

This LO requires an understanding of the satellites concept in NMR spectroscopy, originating from coupling with nuclei whose NMR active isotopes are not 100% abundant.

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.

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: 

First use of the term "bioinorganic"

Submitted by Joshua Telser / Roosevelt University on Wed, 03/19/2014 - 20:19
Description

Thanks to information first provided to me by Prof. Brian M. Hoffman, Northwestern University, I believe that the first documented use of the term "bioinorganic chemistry" occurred at a meeting held at Virginia Tech (VPI&SU) in June, 1970. This meeting was jointly organized with Canadian researchers and was thus an international meeting.

This meeting resulted in an Advances in Chemistry Series book, which has the following URL:

Water Oxidation Catalyzed by NHC Complexes of Iridium

Submitted by Peter M Graham / Saint Joseph's University on Wed, 02/19/2014 - 12:08
Description

A literature discussion based on an interesting paper from Bernhard and Albrecht about a catalytic water oxidation promoted by irdium complexes featuring abnormal/mesoionic NHC ligands.

I used this in an upper-level Organometallics course after discussing NHC ligands in class.
