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.

CBC (Covalent Bond Classification) Method of Electron Counting

Submitted by Chip Nataro / Lafayette College on Thu, 02/02/2012 - 12:29
Description

This series of slides works through an example of electron counting using the CBC (Covalent Bond Classification) method. It compares and contrasts the classic ionic and covalent methods to the CBC method. The example used in these slides is an exception to the 18 electron rule using the the classic methods, but by CBC classification it is a very common ML4X4 tetravalent 16 electron Ti compound.

Energy Nugget: Methane to Methanol

Submitted by Hilary Eppley / DePauw University on Thu, 01/12/2012 - 05:40
Description

This learning object was developed with a lot of help from B. Scott Williams from the Keck Science Department of the Claremont Colleges for my junior/senior level course in 2009.   This object is a literature discussion on the topic, but Scott and I hope to add a 5-slides about learning object to go with it shortly.   The primary literature article used for the discussion is “Characterization of a Rhodium(I) sigma-Methane Complex in Solution,” by Wesley H. Bernskoetter, Cynthia K. Schauer, Karen I.

Manganese carbonyl calculation addition

Submitted by Adam Johnson / Harvey Mudd College on Mon, 10/03/2011 - 01:00
Description

This is an addendum to the Manganese Carbonyl experiment (linked below).  In this part of the experiment, students carry out high level quantum mechanical calculations of reactants, intermediates, and products in order to determine which of two possible structures is correct.

The History of the 18-Electron Rule

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Sat, 01/22/2011 - 14:58
Description

This learning object focuses on fundamental concepts of organometallic chemistry. I use an article published in the Journal of Chemical Education (Jensen, W.B. "The Origin of the 18-Electron Rule," J. Chem. Educ.

Textbook reviews of organometallic textbooks in the journal Organometallics

Submitted by Barbara Reisner / James Madison University on Thu, 01/06/2011 - 05:52
Description

Organometallics has just published a series of reviews of new organometallic textbooks.
Navarro, O.; Vicic, D. A.; Jensen, C. New Organometallic Textbook Reviews. Organomet. 2011, ASAP, DOI:10.1021/om101126k.

The textbooks that are reviewed are:

1) The Organometallic Chemistry of the Transition Metals, 5th ed. Robert H. Crabtree (Yale University, USA). Wiley: Hoboken, NJ, USA. 2009. ISBN 978-0-470-25762-3.

Student Literature-Based Organometallic Lecture

Submitted by Jeffrey Rood / Elizabethtown College on Mon, 01/03/2011 - 14:42
Description
I taught an advanced inorganic chemistry course for the first time this past fall. I focused strictly on organometallic chemistry and we used Spessard and Miessler's book. Because this book is focused on transition metal organometallics, I wanted the students to appreciate some of the organometallic chemistry of the s- and p-block (and zinc). Students worked in pairs (the class size was 12) and had most of the semester to research the literature and develop a 40-50 minute lecture. I also had them develop homework questions and an in class activity to help engage the other students.
