Exploration of Nitrosyl Complexes

Submitted by Brad Kraft / St. John Fisher College on Mon, 07/30/2012 - 15:33
Description

This in-class activity and the related problem set allows students to discover the linear and bent bonding modes of NO to metals based on VSEPR theory through guided inquiry.  Two examples follow which illustrate how the electrons are counted in NO complexes depending on the coordination mode/formal charge of NO. Students must have had prior practice in counting electrons of complexes to complete the problems.   

Soluble Methane Monooxgenase Spectroscopy

Submitted by Gerard Rowe / University of South Carolina Aiken on Fri, 07/20/2012 - 09:37
Description

Determining the reactive intermediates in metalloenzymes is a very involved task, and requires drawing from many different spectroscopies and physical methods.  The facile activation and oxidation of methane to produce methanol is one of the "holy grails" of inorganic chemistry.  Strategies exist within materials science and organometallic chemistry to activate methane, but using the enzyme methane monooxygenase, nature is able to carry out this difficult reaction at ambient temperatures and pressures (and in water, too!).

Exploring the Nanoworld Innovating through Materials from the University of Wisconsin Madison

Submitted by Patricia Stan / Taylor University on Thu, 07/19/2012 - 13:29
Description

This is a great web resource for all types of nano materials.  There are lesson plans, demos, activites, labs and lots of background information.  It is very easy to navigate and there are videos of the labs so you can see each step - very useful when doing a type of synthesis or technique new to you.

ChemTube3D

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 07/19/2012 - 08:51
Description

ChemTube3D is a website maintained by the University of Liverpool that has interactive 3D animations ans structures.  The content is broken up into several areas:

  • A Level;
  • Organic Reactions;
  • Structure and Bonding;
  • Polymers;
  • Solid State.

There is a lot of information on the site, and the information could be used in many courses.  The areas that I find most useful in my sophomore-level inorganic chemistry course.

C(sp3)-F Activation through an Initial C(sp3)-H Activation Mechanism

Submitted by John Lee / University of Tennessee Chattanooga on Wed, 07/18/2012 - 16:35
Description

This paper is from a Science article from Alan Goldman’s group at Rutgers University. It was one of the literature articles that was assigned during the IONiC VIPEr Workshop in July 2012.  In conjunction with reading the article, workshop participants attended a seminar presented by Alan Goldman on this work.

Colored Note Cards as a Quick and Cheap Substitute for Clickers

Submitted by Chris Bradley / Mount St. Mary's University on Tue, 07/17/2012 - 10:23
Description

For many years I have resisted using clickers, mainly because at our university there is no standard universal clicker. I wanted to keep student costs as low as possible but also desired the type of live feedback during a lecture that clicker questions can provide. In both my general chem. (200-300 students) and upper division courses (50-75 students), I now pass out 4 or 5 colored notecards on the first day of class and make sure everyone has one of each color.

Polypropylene Stereochemistry and Identification by 13C NMR Spectroscopy

Submitted by Shirley Lin / United States Naval Academy on Mon, 07/16/2012 - 11:55
Description

These 6 slides introduce the nomenclature used to describe the stereochemistry of various polypropylenes (PPs) that can be synthesized by metallocene-catalyzed polymerizations. Although PP is the specific polymer discussed, the nomenclature applies to other alpha-olefin polymerizations.

Application of Organometallic Chemistry – Breaking the Inert C-H Bond

Submitted by John Lee / University of Tennessee Chattanooga on Mon, 07/16/2012 - 11:39
Description

This learning object is a literature discussion based on a paper published in Nature (Labinger, J. A.; Bercaw, J. E. Nature 2002, 417, 507-514; doi:10.1038/446391a) discussing the mechanisms of C-H activation by transition metal complexes. This is a topic that could be covered at the end of a section on organometallic chemistry that shows a “newer” application.

Metal MACiE Database

Submitted by Anthony L. Fernandez / Merrimack College on Mon, 07/16/2012 - 11:21
Description

As a non-bioinorganic chemist, I am always looking for resources to help me teach bioinorganic chemistry in both my sophomore-level and advanced inorganic chemistry courses.  The "metalloproteome" was the subject of an article in the December 12, 2011 issue of C&E News ("Merging Metals into Proteomics: Tackling the Systematic Study of Metalloproteins").  In this article, the author mentions a new database, called Metal MACiE, of metals in metalloenzymes.

Five Slides About Percent Buried Volume (%Vbur)

Submitted by Chip Nataro / Lafayette College on Mon, 04/23/2012 - 09:29
Description

These slides present a walkthough of performing a Percent Buried Volume (%Vbur) calculation. The %Vbur is a measurement of the bulk of a ligand coordinated to a transiton metal. The calculation uses the crystal structure of a compound to determine how much space a ligand occupies. It does this by placing the metal at the center of a sphere and then calculates the volume of that sphere occupied by the ligand. Originally developed for N-heterocyclic carbene (NHC) ligands, it has also been applied to mono- and bidentate phosphines.
