Evaluating Catalysis Data in High Impact Journals

This assignment is intended as an introduction to searching the chemical literature to identify an article on specific topic (in this case a specific metal within a specified time range). Once they have located their articles, they are expected to name a metal complex and give the oxidation state, d electron count, and geometry.
As a non-bioinorganic chemist, I am always looking for resources to help me teach bioinorganic chemistry in both my sophomore-level and advanced inorganic chemistry courses. The "metalloproteome" was the subject of an article in the December 12, 2011 issue of C&E News ("Merging Metals into Proteomics: Tackling the Systematic Study of Metalloproteins"). In this article, the author mentions a new database, called Metal MACiE, of metals in metalloenzymes.
This in class activity focuses on the ambidentate ligand thiocyanate. Students compare data for known compounds to data for unknowns to make the bonding assignments. Data is provided from Baer, C.; Pike, J. J. Chem. Ed. 2010, 87, 724 where the authors have the students synthesize all the compounds and then complete the data analysis. My course does not include a lab component but I want the students to use literature to support their learning.
Searching and reading the literature is an important tool in teaching organometallic chemistry. This overall project focuses on the improving students' writing skills and to begin to think critically about articles in the literature through a series of different writing assignments. This project is used in a semester long course on organometallics and reaction mechanisms. The first assignment (this LO) is a summary, the second is related to the NSF highlight, and the third is a literature critique.
The synthesis of the nitrogen triiodide ammoniate shock-sensitive explosive is a simple laboratory exercise, but it does require a lengthy time for the material to dry before it is active. This activity uses that time to have students investigate some simple thermodynamics behind their explosive, as well as consult the literature on high energy density materials from the work of Karl O. Christe.
There is also a shorter version of the activity posted as an in-class activity that omits most of the literature investigation.
The covalent bond classification (CBC) method is a way to count electrons for transition metal compounds. It classifies ligands based on their type, either L, X or Z. This is the website for all things CBC. It contains a library which list useful materials for teaching CBC including books that teach the CBC method. The site also has teaching materials that contain MLX plots for all of the transition metals. The MLX plots are charts that show various electron counts and valence for a given metal.
This screencast is a brief introduction to some of the features of VIPEr.
These slides present a walkthough of performing a Percent Buried Volume (%Vbur) calculation. The %Vbur is a measurement of the bulk of a ligand coordinated to a transiton metal. The calculation uses the crystal structure of a compound to determine how much space a ligand occupies. It does this by placing the metal at the center of a sphere and then calculates the volume of that sphere occupied by the ligand. Originally developed for N-heterocyclic carbene (NHC) ligands, it has also been applied to mono- and bidentate phosphines.
A little more than 5 slides, this is a video I made for a colleague to use in General Chemistry as an intro, or hook, into exciting topics in chemistry (in this case, bioinorganic). I use these slides as an intro to my junior/senior Inorganic course on the first day of class, to ask the question "What is Inorganic Chemistry?" and get them to think about the "living" parts of "inorganic". Topics include an overview of essential, toxic, and medicinally active elements of the periodic table, key examples of metalloprotein active sites, and an overview of the functional roles of biological in
