The Color and Electronic Configurations of Prussian Blue

Submitted by EGunn / Simmons College on Mon, 01/05/2015 - 14:47
Description

I used this paper to illustrate several course concepts related to materials structure (crystal lattice structure, coordination number, crystal field theory and orbital splitting, symmetry, electronic spectra, allowed and forbidden transitions). This activity was paired with a laboratory experiment (see related VIPEr objects) in which students synthesized Prussian Blue, and gave students a really in-depth look at what was going on when they mixed those solutions together.

d-Orbital Splitting Patterns in a Variety of Ligand Geometries

Submitted by Anthony L. Fernandez / Merrimack College on Mon, 12/29/2014 - 10:43
Description

In this activity, the provided d orbital splitting patterns need to be matched with ligand geometries. Students are provided with the d orbital splitting diagrams for 6 ligand geometries (octahedral, trigonal bipyramidal, square pyramidal, tetrahedral, square planar, and linear). A web browser is used to view an animation (developed by Flick Coleman) which allows for the visualization of the relationship between the positions of the metal d orbitals and the ligands. Given this information, students should then be able to qualitatively rank the orbitals from highest to lowest energy.

Literature Discussion of Hexamminecobalt(III) – Probing Metal Ion Binding Sites in Nucleic Acids by NMR Spectroscopy

Submitted by EGunn / Simmons College on Tue, 12/09/2014 - 13:56
Description

I use this literature discussion in my second year inorganic class as a follow-up to a lab experiment where students synthesize Werner complexes and then (with much guidance) analyze their IR spectra using symmetry and group theory arguments. This paper provides an excellent example of how cobalt complexes are used in modern applications, and serves as a bridge to bioinorganic chemistry, which is a central feature later in the course.

What Can Go Wrong: A Research Lab Safety Activity

Submitted by Karen McFarlane Holman / Willamette University on Tue, 10/07/2014 - 03:15
Description

Late in their junior year and into the first two months of their senior year, chemistry majors at Willamette write and submit a research proposal.  Shortly before entering the lab for their thesis work, I lead this activity that takes place in our Senior Projects seminar class.  The class meets one hour per week and we cover topics such as how to write an effective grant proposal, ethics in science, presenting data, etc., as well as this safety activity.

Learning from UCLA

Submitted by Sheri Lense / University of Wisconsin Oshkosh on Sat, 09/20/2014 - 19:47
Description

This learning object is designed to spark discussion and educate students taking an inorganic chemistry course about laboratory safety.  It uses the article "Learning from UCLA" by Jyllian N. Kemsley (Chemical & Engineering News (2009), Vol. 87 Issue 31, pp.

Ligand Lineup

Submitted by Sheri Lense / University of Wisconsin Oshkosh on Fri, 08/22/2014 - 11:40
Description

This is a kinesthetic activity in which students must utilize knowledge of the σ-donating, π-donating and π-accepting ability of ligands in order to rank the ligands in the spectrochemical series.  Students are each assigned a ligand on a card.  Suggested ligands are I-, Br-, Cl-, F-, ONO-, NO2- OH-, H2O, pyridine, NH3, ethylenediamine, bipyridine, phenanthroline, PPh3, CN- and CO.  Each student must evaluate the π-accepting, π-donating and σ-donating ability o

The Chemistry of Cooley's Anemia: A Case Study

Submitted by Chris Bailey / Wells College on Wed, 08/06/2014 - 11:36
Description

In this case study, information is presented to students in the form of a dialog between a physician and two parents who have just learned that their child has thalassemia (Cooley’s Anemia). The treatment for this disorder requires a lifetime commitment to whole blood transfusion and chelation therapy (both administered on a daily to weekly basis); the biggest obstacle to long term survival is patient non-compliance.

Nitrogen Fixation: A Structural Inorganic Mystery?

Submitted by Jodi O'Donnell / Siena College on Mon, 08/04/2014 - 16:17
Description

 

These slides describe the recent literature on the structure of the iron sulfur cluster of nitrogenase active site, FeMo-co.  Included are: a comparison of industrial vs. biological ammonia production, several crystal structures from the literature including the unknown until recently hypervalent carbon atom in the center, and a brief mention of the troubling sterics of the active site as crystallized.

A Living Syllabus for Sophomore Level Inorganic Chemistry

Submitted by Sheila Smith / University of Michigan- Dearborn on Mon, 08/04/2014 - 16:02
Description

In my sophomore level inorganic course, I have experimented with the idea of a living syllabus as a way to develop my own specific learning objectives and to help the students connect the material to the tasks that will be expected of them in assessing their learning.
