This learning object is a literature discussion based on a paper published in Nature (Labinger, J. A.; Bercaw, J. E. Nature 2002, 417, 507-514; doi:
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.
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.
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
In 2011, I was fortunate to have Nicolai Lehnert come and speak to my bioinorganic class on his work modeling the FeB (non heme iron) center in bacterial Nitric Oxide reductase. He suggested this paper to prepare the students for his talk and I developed this reading guide to help them (the students) get more out of the reading.
This series of slides works through an example of electron counting using the CBC (Covalent Bond Classification) method. It compares and contrasts the classic ionic and covalent methods to the CBC method. The example used in these slides is an exception to the 18 electron rule using the the classic methods, but by CBC classification it is a very common ML4X4 tetravalent 16 electron Ti compound.
I use this exercise in my 400-level Inorganic (Transition Metals) course. Students have been introduced to assigning point groups in a 300- level Inorganic course on bonding theories. Therefore, I combine a review of assigning point groups with the introduction to inorganic nomenclature in my advanced course. This seems to break up the tedium of the rules for nomenclature while stressing that the need for such elaborate names comes from the need to correctly identify one structure among may isomeric possibilities.
I was taught (many years ago) the common misconception that fitting the linearized form of the Eyring equation overstates the error in the intercept because on a 1/T axis, the intercept is at infinite temperature, and the intercept is far from the real data. While researching various methods of data fitting, I stumbled across this great article from the New Journal of Chemistry (New J.
