Teaching Tanabe-Sugano Diagrams

Submitted by Sheila Smith / University of Michigan- Dearborn on Tue, 05/03/2011 - 11:12
Description

For years, I spent 2-3 days a semester working through Tanabe-Sugano diagrams, their development from terms, their evolution from Orgel diagrams, their analysis to give transition energies (the old ruler- trial and error analysis) and nephalauxetic parameters.  Recently, colleagues in VIPEr convinced me that my time in class could be better spent, but I am not willing to completely give up on Tanabe-Sugano.

Exploring Photographic Chemistry

Submitted by Rebecca M. Jones / George Mason University on Wed, 03/09/2011 - 15:27
Description
This set of experiments is a fun way for students to be experience interesting redox chemistry.  I have taught this series of experiments in my first semester junior level inorganic class for the past 5 years.  In part 1, students create salted paper prints with different binders.  Part 2 involves the synthesis of Prussian blue as cyanotypes are formed on paper and cloth.  In part 3, students design t

Pigment Syntheses and Qualitative Analysis

Submitted by Rebecca M. Jones / George Mason University on Wed, 03/09/2011 - 15:13
Description

This set of experiments provides an introduction to simple inorganic synthesis and qualitative analysis of inorganic pigments.  I have taught this series of experiments in my first semester junior level inorganic class for the past 5 years.  In part 1, students synthesize five inorganic pigments.  Part 2 involves identifying an unknown inorganic white pigment by chemical and physical tests.  These

hybrid orbitals for main group and transition metal complexes

Submitted by Adam Johnson / Harvey Mudd College on Tue, 03/08/2011 - 22:58
Description
This handout shows how the s, p and d orbitals of appropriate symmetry can mix in Cnv and Dnh point groups (n = 3-4). A high-level Gaussian calculation serves to "back up" my "back-of-the-envelope" drawings of some of the hybrid orbitals.

Ligand Field Theory in Coordination Complexes- In Class Exercise

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 02/17/2011 - 14:19
Description

This is an In class exercise on the subject of Ligand Field theory.  It reviews nomenclature and introduces ideas of ligand field splitting and spin in transition metal complexes.  It includes both a worksheet for classroom use, a worksheet key which includes some information not on the student worksheet .

The Electronic Properties of tris-(2,2'-bipyridine)-ruthenium(II) Lab Experiment(s)

Submitted by Jared Paul / Villanova University on Wed, 02/02/2011 - 19:41
Description

This is a lab experiment designed to cover an array of techniques, including metal complex synthesis, spectroscopy and electrochemistry.  Overall, the goal is to synthesize the metal complex Ru(bpy)32+, exchange the counter ion to demonstrate changes in solubility, absorbance and emission properties (including excited state quenching through energy and electron transfer, and ground state oxidation), as well as cyclic voltammetry of the complex.

Kinetics of Ligand Substitution Reactions of a Pt(II) Complex

Submitted by Scott Cummings / Dominican University on Sat, 07/17/2010 - 11:47
Description
This inorganic lab experiment, focusing on the kinetics of ligand-substitution reactions of a square-planar Pt(II) complex, involves collecting UV-vis absorption data and analyzing the results to determine a rate law to support one of three proposed mechanisms.

Element Jeopardy!

Submitted by Keith Walters / Northern Kentucky University on Thu, 07/15/2010 - 11:44
Description

Like many inorganic faculty (especially those faced with trying to teach "all" of inorganic chemistry in a one-term junior/senior course), I have found it increasingly difficult over the years to include any significant descriptive chemistry content in my course. Moreover, I have a constant interest in trying to convey some of the "story behind the story" in chemistry, which in this area centers on the discovery of the elements. I was mulling this over at an ACS meeting one time and happened to be in an inorganic teaching session where Josh van Houten (St.

Metals in Biological Systems - Who? How? and Why?

Submitted by Betsy Jamieson / Smith College on Wed, 01/20/2010 - 10:01
Description

This learning object was developed collaboratively by members of the IONiC Leadership Council.  The overall goal is to provide a general overview of metals in biological systems and introduce students to several of the important ideas in the field of bioinorganic chemistry.  Topics include toxic metals, metals used in biological systems and the overlap of these categories; issues associated with the uptake, transport and storage of metal ions; and the benefits gained by using metals in biological molecules.
