SLiThEr #65: Publishing at PUIs

Submitted by Matt Cranswick / Oregon State University on Tue, 04/01/2025 - 18:36

Join us on Tuesday, April 15 at 2 pm Eastern (11 am Pacific) for a "DIC-structured" seminar in which senior and junior PUI faculty members discuss how they have successfully published research on research project(s) with undergraduate students. Kyle Grice (DePaul) and Jacob Lutter (University of Southern Indiana) will present on how they have been successful in designing and publishing research at their respective PUI. 

Scandium Carbonyls - mysterious myth or legendary legend?

Submitted by James F. Dunne / Central College on Thu, 03/06/2025 - 14:36
Description

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

Adducts of XeO3

Submitted by Chip Nataro / Lafayette College on Wed, 02/26/2025 - 14:03
Description

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.

Geometry of macrocyclic Cu complexes

Submitted by James F. Dunne / Central College on Wed, 02/26/2025 - 12:19
Description

This literature discussion introduces students to various tetradentate ligands not commonly seen in textbooks.  Students can apply knowledge of ligand binding to predict coordination geometry while exploring how the 3D nature of more complex ligands can affect their coordination to a metal.

AsF5 - a superacid for super review!

Submitted by James F. Dunne / Central College on Fri, 02/21/2025 - 13:02
Description

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.

Flipping Cobalt Spin States

Submitted by James F. Dunne / Central College on Fri, 02/21/2025 - 12:01
Description

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.

Eight Coordinate Zirconium?

Submitted by James F. Dunne / Central College on Fri, 02/21/2025 - 11:43
Description

This discussion is intended as a brief application of symmetry and ligand coordination to a novel Zr compound. Students apply VSEPR and molecular symmetry to an uncommon organometallic compound, and apply the coordination mode to basic reactivity. It is intended for an in-class activity but could easily be assigned as a short homework assignment.

Exploring the Electronegativity and Hardness of the Noble Gases

Submitted by James F. Dunne / Central College on Fri, 02/21/2025 - 11:15
Description

This is a literature discussion focused on calculating and comparing the Mulliken electronegativites of the noble gases. Students can explore how this periodic property extends into the noble gases and impacts the observed reactivity of Group 18 compounds.  The discussion could be used either as an in-class activity or a homework assignment.

Come SLiThErIn' Back

Submitted by Chip Nataro / Lafayette College on Mon, 02/10/2025 - 15:25

Join us for a discussion about the 2023 ACS Guidelines for Undergraduate Chemistry Programs with Michelle Brooks (Assistant Director of the Office of Higher Education at ACS), Cora MacBeth (Emory University) and Barb Reisner (James Madison University). This event will take place on 2/18 at 5 pm eastern. The speakers will provide an overview of the Guidelines with an opportunity for Q&A. This will be followed by a conversation about guidelines for developing and teaching inorganic chemistry courses. The goal is to solicit feedback from the community.
