3D Printed Crystal Structure Activity

Submitted by Chris Stromberg / Hood College on Wed, 03/19/2025 - 18:49
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?

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.
