2025 Nobel Prize in Chemistry - MOFs
In celebration of the 2025 Nobel prize in Chemistry awarded to Susumu Kitagawa, Richard Robson and Omar Yagi, this collection features various LOs about MOFs.
Metallocene cations and anions
Chip Nataro / Lafayette College
Tue, 09/23/2025 - 11:39
Description
This is a really interesting paper in J. Am. Chem. Soc. (2025, 147, 34641-34646) involving a complex salt in which both the cation and anion are metallocenes. While a majority of the paper is focused on the characterization of two new compounds, it presents some excellent opportunities to practice counting electrons, one of which was a challenge to this author.
Rhenium isocyanide complexes from the Figueroa group
Description
This literature discussion is in honor of Dr. Josh Figueroa, recipient of the 2026 F. Albert Cotton Award in Synthetic Inorganic Chemistry. Josh has done some tremendous work with isocyanide ligands and this paper is but a brief glimpse into this field. The complexes of interest contain carbonyl ligands and isocyanide ligands, so there are plenty of opportunities for students to use group theory to predict the number of IR-active vibrations for these ligands.
SLiThEr #64: Developing ACS Guidelines for Undergraduate Chemistry Programs
Description
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). Additional discussion is available to registered faculty users.
SLiThEr #63: Catching up with Reilly and Sydney
Description
This goes back to SLiThEr #14 when we interviewed two senior undergraduates in the midst of the COVID pandemic. At the time of this SLiThEr, both are in graduate school and getting close to their PhD.
Reilly Gwinn (Virginia Tech) and Sydney Towell (UNC - Chapel Hill) update us on their career paths.
From Whiteboard to Spartan: An Integrated Exploration of H2A Molecular Orbitals and Molecular Geometry
Description
This two-part activity offers an integrated approach to understanding molecular orbitals and molecular geometry. In class, students will first engage in a hands on, qualitative construction of the H2O molecular orbital diagram using symmetry principles and a whiteboard.
Hydrocyanation
Description
This literature discussion was inspired by a talk given by Dr. Nora Radu, recipient of the 2025 ACS Award for Distinguished Service in the Advancement of Inorganic Chemistry. It is a bit 'big picture' in nature in that the hydrocyanation reaction is important for the synthesis of nylon. As such, there is a significant amount of background material relating to nylon-6,6. Students will read an article from C&EN, portions of a patent, and portions of an article from J. Chem.
COMFORT, A web resource for fragment molecular orbitals of simple fragments
Description
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.
3D Printed Crystal Structure Activity
Description
This exercises uses beads to help show how different crystal structures are formed. The exercise includes 3D-printed boxes with starting structures incorporated in the bottom to increase the stability of structures that students build. The exercise also includes a number of additional 3D-printed manipulatives to help students visualize the unit cells and other properties of different crystal structures. These include unit cells with accurate atomic and hold dimensions and several different ways to visualize the layer structures in close-packed structures.
Scandium Carbonyls - mysterious myth or legendary legend?
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
