Employing 2D NMR and NOE to assign protons in an organometallic complex

Submitted by Sherzod / Northwestern University on Mon, 07/14/2014 - 18:00
Description

The following paper will be given to the students to read at home along with the questions in the attached document. Students will be allowed to discuss their answers in small groups and refine their answers, before the corresct answer is revealed.

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.

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.

A Review of 3DMolSym: A Web Resource for Teaching Molecular Symmetry

Submitted by Marion Cass / Carleton College on Fri, 05/23/2014 - 19:22
Description

Introducing you to 3DMolSym:  A Web Resource for Teaching Molecular Symmetry that uses Adobe Shockwave for Visualizations and Animations.

Note there is a slight difference when operating this resource on a Mac or in a Windows Operating Systerm.  On a Mac if you don't change an item (any item) in the pull down menu on the right when the resouce opens, the selection of molecules will be frame shifted by one molecule.  An easy fix is described in the Description below.

Viewing Jmol Images and Animations (currently blocked) that call a Jmol Applet

Submitted by Marion Cass / Carleton College on Thu, 03/13/2014 - 22:31
Description

 

    Every day when I teach Inorganic Chemistry (and in most of my problem sets and take home exams) I create Web pages to show 3D images of selected molecules to my students.  I am a visual learner and I find the structures beautiful and informative.

    In the past few months, you likely have found that web sites scripted with Jmol scripts calling a Jmol applet (which is a Java applet) are blocked. 

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.

 

Student choice literature-based take home exam question

Submitted by Hilary Eppley / DePauw University on Fri, 01/24/2014 - 15:27
Description

During my junior/senior level inorganic course, we did several guided literature discussions over the course of the semester where the students read papers and answered a series of questions based on them (some from this site!).  As part of my take home final exam, I gave the students an open choice literature analysis question where they had the chance to integrate topics from the semester into their interpretation of a recent paper of their own choice from Inorganic Chemistry, this time with limited guidance.

IC Top 10 first day activity

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 09/05/2013 - 09:32
Description

I modified the Barb Reisner/Joanne Stewart/Maggie Geselbracht First Day TOC activity (https://www.ionicviper.org/class-activity/introducing-inorganic-chemist…) to take advantage of the quarterly list of Top 10 Most Read articles that IC sends out.  This is delivered to me as an email from ACS pubs and I am sure that it is available to anyone who wished to subscribe to the updates.  I have attached a pdf copy of the August 2013 update as an example.
