Otterbein Symmetry In-Class Activity/Take home activity
Description
This is an in-class activity I made for my students in a Junior/Senior-level one-quarter inorganic course.
Unfortunately it was waaay too long for the 1.5 h class (i gave them about 45 min). I recommend taking this and adapting it to a take-home exercise or homework set, which is probably what I will do this coming year.
Students used Otterbein to look at various structures, starting with low symmetry, working up to very high symmetry structures. I had them go through the "challenge" so they couldn't see the keys at first, but then go back to check their answers.
Synthesis and Characterization of a Series of Organometallic Ru(II) Complexes with Fluorinated Phosphine and Phosphite Ligands
Description
In this experiment, students will synthesize and characterize a series of Ru(II) p-cymene piano-stool complexes.
Point Group Battles Activity
Description
In this activity, a pair of students are show an object or molecule and are asked to determine the point group before their competitor.
Iron Cross-Coupling Catalysis
Description
In this experiment, students will synthesize and characterize an iron complex followed by completion of two series of catalytic cross-coupling reactions mimicking the methodology utilized by organometallic chemists to balance catalyst efficacy and substrate scope. Initially the complex Fe(acac)3 [acac = acetylacetone] is prepared. Two sets of catalytic reactions are completed: one comparing different iron catalysts (Fe(acac)3, FeCl2, FeCl3) while the other compares substrates (4-chlorotoluene, 4-chlorobenzonitrile, 4-chlorotrifluorotoluene).
Antibacterial Reactivity of Ag(I) Cyanoximate Complexes
Description
In this experiment, students will synthesize and characterize one of three Ag(I) cyanoximate complexes as potential antimicrobial agents for use in dental implants. This experiment combines simple ligand synthesis, metalation and characterization, and a biomedical application. The complexes are both air and light stable.
A Demonstration to Segue Between d to d and CT Transitions
Description
The following is a simple in-class “demonstration” that I use to segue between d to d and charge transfer transitions. After teaching about d to d transitions and Tanabe-Sugano Diagrams, I show my students three solutions that I have put in large test tubes before class. The three solutions I place in the test tubes are:
a. 10 ml of 0.1M Co(H2O)62+
b. 10 ml of 0.1M Cu(H2O)62+
c. 10 ml of a freshly prepared 0.1 M KMnO4 solution
Peer Review - How does it work?: A literature discussion with a focus on scientific communication
Description
This learning object is based on discussion of the literature, but it follows a paper through the peer review process. Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots. There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.
Analyzing a journal article for basic themes, roles of authors, and the scientific method
Description
This literature discussion is meant to give students an understanding of both the key concept-driven and more “meta” information of a literature paper. Students will use Jillian Dempsey’s paper, “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface-adsorbed hydrogen-evolving species,” to investigate paper authorship, how the scientific method is used in research, and how to understand the important findings of a research article.

A discussion on "Electrochemical formation of a surface-adsorbed hydrogen-evolving species"
Description
The paper entitled “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface adsorbed hydrogen-evolving species” explores the discovery, characterization and catalytic activity of a film that deposited on the electrode while studying a nickel complex under electrocatalytic conditions.
This literature discussion includes several sets of questions that address different aspects of the paper, as described in the implementation notes.
