The Structure and Color of Alums

Submitted by EGunn / Simmons College on Mon, 07/14/2014 - 13:09

This is an in-class assignment designed to help students integrate their understanding of periodic trends and materials properties. Using the color of alum crystals as an example of octahedral coordination chemistry, students use their knowledge of electronic structure and periodic trends to predict which of the isomorphous alum crystals will be colored, and to qualtitatively rank the degree of crystal field splitting in a family of alum crystals.

Dissecting Catalysts for Artificial Photosynthesis

Submitted by Anne Bentley / Lewis & Clark College on Mon, 07/07/2014 - 13:57

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.

Hard Soft Acid Base Theory - Coordination Trends in Alkali Metal Crown Ether Uranyl Halide Complexes: The Series [A(Crown)]2[UO2X4] Where A = Li, Na, K, and X = Cl, Br

Submitted by Gerard Rowe / University of South Carolina Aiken on Tue, 07/01/2014 - 11:13

In this literature discussion, students are asked to read an article describing a series of uranyl halide compounds that contain an alkali counterion that interacts with one or more of the uranium's ligand atoms.  This paper stands out as a great example of the binding preferences of acids and bases, and can be explained very well using simple HSAB concepts.

Student choice literature-based take home exam question

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

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.

QSAR and Inorganic Chemistry

Submitted by Vanessa / Albion College on Thu, 06/27/2013 - 14:59

This presentation provides a short introduction to Quantitative Structure-Activity Relationships and its use in Inorganic Chemistry. A brief introduction to Linear-Free Energy Relationships and the Hammett Equation is given, followed by three examples of how QSARs have been used in inorganic chemistry. 

Concept mapping the primary literature: "Compositionally Tunable Cu2ZnSn(S1-x,Sex)4 nanocrystals"

Submitted by Benny Chan / The College of New Jersey on Thu, 06/27/2013 - 09:26

Concept maps are a visual way to organize and represent information. In this literature discussion, we introduce a novel technique for teaching literature analysis to students where concept maps are used for establishing relationships between the key ideas, theories, procedures, and methods of a proposed literature article. Using the article “Compositionally Tunable Cu2ZnSn(S1-xSex)4 Nanocrystals: Probing the Effect of Se-Inclusion in Mixed Chalcogenide Thin Films” (Riha, S.C.; Parkinson, B.A.; Prieto, A.L. J. Am. Chem.

Literature summary through student presentation - free choice of topic.

Submitted by Cameron Gren / University of North Alabama on Wed, 06/26/2013 - 07:59

(1) Student choses and reads a journal article of his/her choice that is related to a topic we have discussed during the semester. (i.e. atomic structure, MO theory, group theory, solid state structure, band theory, coordination chemistry, organometallics, catalysis). Suggested journals include, but are not limited to JACS, Inorg. Chem., Organometallics, Angew. Chem., JOMC, Chem. Comm.)

(2) Student answers the following questions regarding their chosen article:

    (a) Describe, in 1 or 2 sentences the goal of this work. 

Trends in Measured Redox Potentials and Computed Molecular Orbital Energies of Derivatized Buckminsterfullerenes

Submitted by Robert Q. Topper / Cooper Union on Tue, 06/25/2013 - 01:55

In this project students are asked to reproduce published calculations of molecular orbital energies of a series of derivatized fullerenes and correlate them with published reduction and oxidation potentials obtained from cyclic voltammetry. The particular subset of the derivatives to be studied are chosen by the student and this choice is part of the learning activity. The students then carry out additional calculations using other theoretical models to see whether they improve the correlation between computed and experimental properties.

Lithium Diazenide Surprise!

Submitted by Maggie Geselbracht / Reed College on Fri, 05/31/2013 - 23:00

Students in a sophomore-level inorganic chemistry course were asked to read the paper “High-Pressure Synthesis and Characterization of the Alkali Diazenide Li2N2” (Angew. Chem. Int. Ed. 2012, 51, 1873-1875. DOI: 10.1002/anie.201108252) in preparation for a class discussion.  For many students, this was a first exposure to reading the primary literature. 

General Chemistry Electronic Study Aids

Submitted by David Kreller / Georgia Southern University on Sun, 04/21/2013 - 13:14

At this website students can access interactive game-like learning resources that cover a wide range of topics in general chemistry.  These learning activities, which are in the form of flash cards, quizzes and matching games, will help student learn and review/drill important general chemistry topics.
