Relating Ligand Field Theory to Nickel Complex Color

Submitted by Joya Cooley / California State University, Fullerton on Tue, 06/28/2022 - 14:55
Description

This In-Class Activity is meant to follow up discussions of ligand field theory toward the end of MO theory including the effects of sigma donors, pi donors, and pi acceptors, and how it relates to absorption spectra and observed color of some transition metal complexes. Students have learned crystal field theory and the effects of geometry/symmetry on ∆, then we extend to LFT and how the chemistries of different ligands affect ∆.

1FLO: Perhalogenated Carba-closo-dodecaborate Anions as Ligand Substituents: Applications in Gold Catalysis

Submitted by Megan Mohadjer Beromi / United States Naval Academy on Mon, 06/27/2022 - 19:58
Description

This 1FLO focuses on the fundamentals of catalysis and the interpretation of catalytic data. The questions guide students through the definition of catalysts, turnover frequency, turnover number, and require the students to extract information from a table of catalytic data. The data set comes from the unprecedented activity of carba-closo-dodecaborate ligated gold catalysts in hydroamination reported by Lavallo and coworkers in 2013 (Lavallo, V.; Wright II, J. H.; Tham, F. S.; Quinlivan, S. Angew. Chem. Int. Ed. 2013, 52, 3172.

Substitution Chemistry in Odd-Electron Iron Group Carbonyl Complexes (D'Acchioli)

Submitted by Nancy Williams / Scripps College, Pitzer College, Claremont McKenna College on Sun, 05/29/2022 - 05:54
Description

This LO brings together organometallic chemistry, electrochemistry, and computational chemistry in a complete whole, and shows how these different expertises and techniques all can add to our understanding of a rich chemical system. It might be of particular interest in a class dominated by even-electron and diamagnetic chemistry to give students an understanding of how practitioners approach odd-electron, paramagnetic systems. 

Mechanistic Study of Competitive sp3-sp3 and sp2-sp3 Carbon-Carbon Reductive Elimination from a Platinum(IV) Center and the Isolation of a C-C Agostic Complex (Williams)

Submitted by Shirley Lin / United States Naval Academy on Fri, 05/20/2022 - 08:09
Description

This literature discussion focuses on a J. Am. Chem. Soc. communication that describes a series of Pt complexes that exhibit competitive reductive elimination reactions to form either an sp2-sp3 bond or an sp3-sp3 bond. One of the complexes also contains a C-C agostic interaction with the metal. The questions are written to be addressed by students in a foundation-level inorganic course.

Inorganic Chemistry

Description

The wave nature of electrons is applied to atomic structure and periodic trends. Inter and intramolecular bonding models are used to interpret the chemical and physical properties of various materials, from simplistic diatomic molecules to structurally complex molecular and ionic systems.
