In this experiment, students will synthesize a cobalt Schiff base complex with varying axial ligands ([Co(acacen)L2]+). They will characterize the complex using various techniques, and may perform computational modeling to predict spectroscopic properties.
This is a literature discussion based on the paper “Spectroscopic Elucidation of the Inhibitory Mechanism of Cys2
Students are asked to read an article detailing the development of a cobalt-based MRI contrast agent ("A Redox-Activated MRI Contrast Agent that Switches Between Paramagnetic and Diamagnetic States", Tsitovich, P. B.; Spernyak, J. A.; Morrow, J. R. Angew. Chem. Int. Ed. 2013, 52, 14247-14250, DOI: 10.1002/anie.201306394). Before coming to class the students are asked to answer a series of questions designed to guide them through the first half of the article, and to be prepared to discuss their answers in class.
The Diatom Thalassiosira weissflogii is very resilient. It thrives in poor quality water, where high CO2 levels, chlorine and cadmium ion concentrations, and pH are observed. How is it possible for cadmium ions to be a nutrient for this diatom, when it is normally seen as a toxin in biological systems?
This LO introduces students to bioinorganic chemistry using the enzyme carbonic anhydrase to illustrate biodiversity, adaptation, HASB theory, metal ion ligand bonding as represented by the PDB using Ligand Explorer, and more.
This is an in-class discussion of an article that appeared in The Economist. It can be used to review several topics covered in the first year chemistry class.
This experiment involves the preparation of a key starting reactant in high purity and yield for an ongoing research project, specifically for the development of potential photodynamic therapy (PDT) agents. The students synthesize [ReO2(py)4]Cl.2H2O using standard inorganic synthesis techniques. The students visualize the vibrations and electronic properties (e.g. molecular orbitals) of the compound using output files generated from density functional theory (DFT).
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.
This Five Slides About was prepared specifically for the 2014 IONiC/VIPEr workshop Bioinorganic Applications of Coordination Chemistry held at Northwestern University July 13-18, 2014.
Anne asked the students in her junior/senior inorganic course to develop their own literature discussion learning objects and lead the rest of the class in a discussion of their article. Each student chose one article from a list of suggestions provided. Student Hayley Johnston chose this article describing a Mn-containing catalyst for carbon dioxide reduction (Jonathan M. Smieja, Matthew D. Sampson, Kyle A. Grice, Eric E. Benson, Jesse D. Froehlich, and Clifford P.
