Chapter 10--Stanley Organometallics

Submitted by George Stanley / Louisiana State University on Mon, 08/14/2017 - 12:32
Description

Chapter 10 from George Stanley's organometallics course, M-M bonding

 

this chapter covers bonding and structure of metal-metal bonds and some descriptive chemistry.

The powerpoint slides contain answers to some of the in-class exercises, so those are behind the "faculty only" wall. I share these with students after the class, but not before.

Everyone is more than welcome to edit the materials to suit their own uses, and I would appreciate being notified of any mistakes that are found.

Investigating the toxicities of metals and identifying cadmium centers in metallothioneins

Submitted by Chantal Stieber / Cal Poly Pomona on Sat, 06/03/2017 - 14:43
Description

This activity was designed as an in-class group activity, in which students begin by using basic principles to predict relative toxicities and roles of metals in biological systems. Students then learn about the structures of metallothioneins using information from the protein data bank (PDB) and 113Cd NMR data. By the end of the activity, students will have analyzed data to identify and determine bonding models and coordination sites for multiple cadmium centers in metallothioneins. It is based on recent literature, but does not require students to have read the papers before class.

Introduction to Agostic Interactions

Submitted by Emma Downs / Fitchburg State University on Sat, 06/03/2017 - 11:59
Description

A brief introduction to agostic interactions and their importance to common organometallic mechanisms such as beta-hydride elimination. Examples of compounds containing these interactions are discussed and compared to familiar molecules such as diborane. Ways to characterize these interactions are also introduced.

Slides are based on the PNAS review Agostic Interactions in Transition Metal Compounds

Literature Discussion of R3CH→ SiFR3 Agostic Interactions

Submitted by tgupta / South Dakota State University on Sat, 06/03/2017 - 11:53
Description

The set of questions in this literature discussion activity is intended to engage students in reading and interpreting scientific literature and to develop a clear and coherent understanding of agostic interactions.

Fivefold Bonding in a Cr(I) Dimer Updated and Expanded

Submitted by T Brown / SUNY Oswego on Sat, 06/03/2017 - 10:46
Description

This paper describes the synthesis and characterization of a Cr(I) dimer with a very short Cr-Cr distance. Computational studies support fivefold bonding between the chromium atoms. This paper could be used to introduce metal-metal multiple bonds and discuss the molecular orbital interactions of homonuclear diatomics including d-orbitals. More generally, it is a nice example to stimulate the discussion of what constitutes a bond and the various interpretations of bond order.
