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.
This literature discussion focuses on a 2022 Nature Comm paper looking at the reasons behind the pyramidal structures of tri-coordinate f-element complexes. There is plenty to discuss in terms of bonding and coordination geometries in metal complexes, and the effects of pressure on coordination geometry.
Organometallic Precursor in [FeFe] Hydrogenase H-Cluster Bioassembly (Britt)
In Fall 2022, R. David Britt was awarded the ACS Alfred Bader Award in Bioinorganic Chemistry for pioneering pulse electron paramagnetic resonance (EPR) spectroscopy of the photosystem II oxygen-evolving complex, plus the advanced EPR spectroscopic characterization of numerous and varied key metalloenzymes and catalysts.
A Thousand Manipulatable Inorganic Electron-Counting Problems from Crystallography
Building Heteronuclear Diatomic MOs
A guided inquiry activity for students to build the MO diagram for HF based on energetic and symmetry considerations. Students then compare their model to a standard MO diagram and examine what additional information a MO diagram conveys that the Lewis structure does not.
Phosphate Reduction by Mechanochemistry (Cummins)
This Literature Discussion LO was created for the ACS Inorganic Chemistry Award Winners. Dr. Kit Cummins was the recipient of the 2023 Frederick Hawthorne Award in Main Group Inorganic Chemistry. This LO is based on a recent paper from the group of Dr. Cummins, entitled "Sustainable Production of Reduced Phosphorus Compounds: Mechanochemical Hydride Phosphorylation Using Condensed Phosphates as a Route to Phosphite", published in ACS Central Science, 2022, 8, 332-339.
In SLiThEr #39 Chip Nataro (Lafayette University) introduces us to the discussion LOs he uses in his senior-level inorganic course and the topics covered.
This literature discussion is based on a 2022 Science paper describing a series of dilanthanide complexes with exceptional magnetic properties due to the presence of metal-metal bonding. These molecules are the first reported species to feature direct bonding between two lanthanides! The paper contains ample material for discussion of molecular symmetry and bonding, oxidation states and electron configurations, and magnetism. The handout includes a description, glossary, discussion questions, and pre-class worksheet.
