This screencast is a brief introduction to some of the features of VIPEr.

19F NMR In-class exercise

Submitted by Sheila Smith / University of Michigan- Dearborn on Mon, 04/04/2011 - 12:27
Description

This is an in class activity to introduce the topic of multinuclear NMR, which is not covered (beyond 13C) in our sophomore level organic course. It is designed to walk the students through the process of predicting NMR spectra, as they learned in sophomore organic chemistry, but for a different I=1/2 nucleus, in this case 19F, which is I=1/2 and 100% abundant. 

 

The [XeF]+ Cation and Ion-Pairing in [MF6]– and [M2F11]– Salts (M = As, Sb, Bi)

Submitted by Maggie Geselbracht / Reed College on Sat, 03/19/2011 - 17:53
Description

This Lewis structure and VSEPR problem is based on a paper from Inorganic Chemistry in 2010 reporting the crystal structures of a series of salts of the [XeF]+ cation.  The [MF6]– and [M2F11]– anions (M = As, Sb, Bi) were used as counterions, and in all cases, the [XeF]+ cation interacts with the anion via a weak bond between the Xe and a fluoride of the anion to form an ion-pair in the crystalline solid.  These somewhat unusual ions provide an interesting application of the predictive powers of Lewis stru

The Extremely Explosive Carbonyl Diazide Molecule

Submitted by Maggie Geselbracht / Reed College on Sat, 03/19/2011 - 17:03
Description

This Lewis structure and VSEPR problem is based on a paper from Inorganic Chemistry in 2010 reporting the crystal structure of the carbonyl diazide molecule.  This relatively simple molecule provides an interesting application of the predictive powers of Lewis structures and VSEPR theory to molecular structure, backed up by experimental data on bond distances and bond angles.  Before tackling carbonyl diazide, the students warm up by considering the structures of hydrogen azide and the isolated azide ion.  The reference to the original paper is

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

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.

First Isolation of the AsP3 Molecule

Submitted by Anne Bentley / Lewis & Clark College on Fri, 09/03/2010 - 13:47
Description

Early in 2009, Christopher Cummins’ group at MIT reported (in Science) the synthesis of AsP3, a compound that had never been isolated at room temperature.  Later that year, a full article was published in JACS comparing the properties and reactivity of AsP3 to those of its molecular cousins, P4 and As4.  The longer article is full of possibilities for discussion in inorganic chemistry courses, with topics including periodic trends, NMR, vibrational spectroscopy, electrochemistry, molecular orbital theory, and coordination chemistry.

12 Slides About African American Contributions to the Chemical Sciences

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Wed, 07/21/2010 - 23:53
Description

This presentation provides a brief overview of the contributions of five AfricanAmerican chemists, including two inorganic chemists. George Washington Carver is quite often themost celebrated African American chemist (soil chemist), but he is only one individual! There are many other African Americans that have made important and significant contributions to the chemical sciences. The profiles include inorganic chemists, namely, Professor Gregory H. Robinson, University of Georgia and Dr. Novella Bridges, Pacific Northwest National Laboratory (PNNL).

Synthesis and Molecular Modeling of Sodium Tetrathionate

Submitted by Kim Lance / Ohio Wesleyan University on Sat, 07/17/2010 - 12:01
Description
This experiment is a computational supplement to synthesis of sodium tetrathionate described in "Macroscale Inorganic Chemistry:  A Comprehensive Laboratory Experience".*  Students will synthesize one sulfur oxyanion (tetrathionate), optimize and compute IR spectra for their synthesized product.   In addition, students will predict (using symmetry arguments) and then compute the IR vibrational modes for six additional sulfur oxyanions.  A comparison of theoretical (IR spectra),
