This learning objective focuses on the enzyme aconitase.  The iron-sulfur cluster is used to regulate iron in the cell and isomerize citrate for energy – two very different mechanisms.  The activity consists of an introduction to the enzyme and a student discussion on the mechanism of the isomerization of citrate to isocitrate; starting in a small group setting followed by a class debriefing.  

This is an in-class assignment designed to help students integrate their understanding of periodic trends and materials properties. Using the color of alum crystals as an example of octahedral coordination chemistry, students use their knowledge of electronic structure and periodic trends to predict which of the isomorphous alum crystals will be colored, and to qualtitatively rank the degree of crystal field splitting in a family of alum crystals.

This is the second part of a two-day class discussion on molecular and inorganic spectroscopy. In this activity, upper level students learn about spectroscopic tecniques used in inorganic chemistry and then devise an experiment to follow the progress of a hypothetical reaction. The activity also prepares students for the inorganic laboratory "Linkage isomerism of nitrogen dioxide" in which infrared spectroscopy is used to monitor changes to the N-O vibrational stretch upon coordination to a metal.

This learning object focuses on a recent publication (Acta Crystallographia 2014, C70, 260 -266) by the Collins research group in the Department of Chemistry at The College of Wooster.  Specifically, the paper evaluates the coordination diversity of a N-donor ligand, 2-phenyl-1,10-phenanthroline(pnp) with three new pnp-metal complexes containing Au(III), Cu(II), and Pd(II) metal centers.
