A collection of all of the IONiC VIPEr SLiThErs (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable). These events are short presentations on a topic followed by a period of discussion between the presenter and live participants. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.
The website entitled COMFORT (https://ipc.iisc.ac.in/~ags/ip312/comfort.html) is a easy way to visualise fragment molecular orbitals of many different organic ligands and also metal fragments. One can match the frontier orbitals of the fragments to see if they can form stable molecules. It helps one to see how fragments of an octahedral organometallic complex can be stripped of its ligands one by one to generate fragments that can match organic ligands with multiple "pi" bonds.
This literature discussion is based on a short JACS communication reporting the first isolable Sc(II) carbonyls (not a typo) and isocyanides. The paper discusses some standard synthesis and characterization while exploring a more fundamental question regarding why Sc, a d-block metal, is considered a rare-earth and when it stops reacting analogously to the rare-earth metals. The LO focuses on ye olde carbonyl stretching frequencies and back-bonding and makes a nice follow up to an introduction to that concept. It tries to make students explicitly connect electron configuration to changes
This literature discussion was prepared as part of the 2025 ACS awards collection in honor of Gary J. Schrobilgen, winner of the M. Frederick Hawthorne Award in Main Group Inorganic Chemistry.
This LO was developed as a review activity for the end of the semester. Students are required to touch on a wide range of topics including acid-base theories, crystal systems, point groups, the spectrochemical series, and 19F NMR spectroscopy. A close reading of the paper is required helping to build student comprehension of the literature.
This activity was designed to assess student comprehension of how changes in pi-donation from ligands can affect both crystal field splitting and metal spin states. The activity requires students to practice electron counting, idealized crystal field splitting, and then apply these concepts to explain the observed change from low to high spin caused by the loss of a proton.
This Literature Discussion considers the synthesis of the first carbene-bismuthinidene complex by Gilliard and coworkers in 2019. This molecule serves as an illustration of different bonding models, as it can be described by multiple resonance structures invoking fully covalent, zwitterionic, and coordinate/dative bonding forms. Students analyze these resonance structures and their geometrical implications, then compare to the experimental structural evidence to come to a conclusion about which bonding model(s) best describe this molecule!
The MoleCVUE website contains several items that should be of interest to the VIPEr community, especially the activities. Each activity is designed to be ready to deploy in lecture, laboratory, or as homework. There are activities covering all of the major subdisciplines of chemistry (some more than others). Some activities that might be of particular interest to VIPEr are "Group Theory", "VSEPR", and "Electron Configurations of Atoms and Ions". All of the activities are written to use WebMO, but could be adapted for other systems. Most activities are doable with the free or demo versi
This is a literature-based end of semester project. After a semester of introducing literature in the form of typical literature discussions, this assignment is given to small groups. It may be easily amended or added to. Each group is provided with a paper and accompanying questions that are similar to the literature discussions they have done over the semester. They then must use these guiding questions to assemble a presentation to the class. The topics chosen and the guiding questions are designed to provide students with a taste of the many areas of inorganic chemistry that are no
This LO was inspired by a talk that Megan Fieser gave at the 2024 Organometallic Chemistry Gordon Research Conference. It was an excellent talk with some really interesting chemistry. Wanting something with practical application for my class focused on organometallic chemistry, I looked at one of her 'older' papers and found this really interesting rhodium catalyst. In the main paper for this LO (Mater. Horiz. 2023, 10, 2047), the catalytic dechlorination of poly(vinyl chloride) (PVC) using a rhodium pincer complex is described.
