Zinc-Zinc Bonds (Expanded and Updated)

Submitted by Wes Farrell / United States Naval Academy on Wed, 06/05/2019 - 11:42
Description

This paper in Science reports the synthesis of decamethyldizincocene, a stable compound of Zn(I) with a zinc-zinc bond. In the original LO, the title compound and the starting material, bis(pentamethylcyclopentadienyl)zinc, offer a nice link to metallocene chemistry, electron counting, and different modes of binding of cyclopentadienyl rings as well as more advanced discussions of MO diagrams.

Quadruple Bond Acrobatics

Submitted by Lori Watson / Earlham College on Tue, 05/28/2019 - 14:40
Description

Four pairs of students represent quadruple bonding in metal complexes by "forming bonds" with a variety of physical methods involving actions like facing each other while holding hands (sigma bond), touch hands and feet of their partner "above and below" the plane (two pi bonds), touching hands and feet while facing each other (delta bond).  This results in a "Twister"-like pile of students resembling the quadruple bonding interaction

 

Advanced ChemDraw (2019 Community Challenge #2)

Submitted by Chantal Stieber / Cal Poly Pomona on Tue, 02/12/2019 - 12:12
Description

This in-class activity was designed for a Chemical Communications course with second-year students. It is the second part of a two-week segment in which students learn how to use ChemDraw (or similar drawing software to create digital drawings of molecules).

5-ish Slides About Bridging Hydrides and the [Cr(CO)5HCr(CO)5] anion

Submitted by Kyle Grice / DePaul University on Thu, 01/31/2019 - 13:52
Description

This set of slides was made for my Organometallics class based on questions about bridging hydrides and specifically the chromium molecule. I decided to make these slides to answer the questions, and do a DFT calc to show the MO's involved in bonding of the hydride.

Submitted by M. Watzky / University of Northern Colorado on Mon, 01/28/2019 - 14:50
Description

This Guided Literature Discussion was assigned as a course project, and is the result of work originated by students Joie Games and Benjamin Melzer.  It is based on the article “Next-Generation Water-Soluble Homogeneous Catalysts for Conversion of Glycerol to Lactic Acid” by Matthew Finn, J. August Ridenour, Jacob Heltzel, Christopher Cahill, and Adelina Voutchkova-Kostal in Organometallics 2018 37 (9), 1400-1409.

Submitted by M. Watzky / University of Northern Colorado on Wed, 01/16/2019 - 19:11
Description

This Guided Literature Discussion was assigned as a course project, and is the result of work originated by students Jana Forster and Kristofer Reiser.  It is based on the article “Mechanism of the Platinum(II)-Catalyzed Hydroamination of 4-Pentenylamines” by Christopher F. Bender, Timothy J. Brown, and Ross A. Widenhoefer in Organometallics 2016 35 (2), 113-125.

Venn Diagram activity- What is inorganic Chemistry?

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 01/03/2019 - 18:02
Description

This Learning Object came to being sort of (In-)organically on the first day of my sophomore level intro to inorganic course. As I always do, I started the course with the IC Top 10 First Day Activity. (https://www.ionicviper.org/classactivity/ic-top-10-first-day-activity).  One of the pieces of that In class activity asks students- novices at Inorganic Chemistry- to sort the articles from the Most Read Articles from Inorganic Chemistry into bins of the various subdisciplines of Inorganic Chemistry.
