Molecular Hydrogen Complexes of Mo and W

Submitted by Kyle Grice / DePaul University on Fri, 11/11/2016 - 19:28
Description

Literature discussion about the first examples of molecular hydrogen complexes isolated by Gregory J. Kubas in the early 80s. The questions are divided into groups with two levels of difficulty.

The more basic group of questions includes topics on:

1)      Coordination Chemistry: electron count, geometry, oxidation state, orbital interactions, types of ligands, binding modes, cis/trans and fac/mer isomers.

2)      Symmetry elements and point groups.

3)      Basic concepts on spectroscopy: NMR, Raman, IR, UV/Vis, XANES, EXAFS, neutron and X-ray diffraction

Ethylene compounds of the coinage metals

Submitted by Chip Nataro / Lafayette College on Mon, 10/17/2016 - 12:55
Description

This is a literature discussion based on a short paper on ethylene compounds of the coinage metals (Dias, H. V. R.; Wu, J. Organometallics 2012, 31, 1511-1517). In this paper, analogous ethylene compounds are prepared with Cu(I), Ag(I) and Au(I). The other ligand on the coinage metal is a scorpionate tris(pyrazolyl)borate ligand. The strength of the interaction between the metal and the ethylene varies significantly with the coinage metal as seen in X-ray crystallographic and spectroscopic (1H and 13C NMR) data.

Chapter 7--Stanley Organometallics

Description

Chapter 7 from George Stanley's organometallics course, Alkenes and Alkynes

 

this chapter covers bonding and structure of metal pi-bonds, some descriptive chemistry, and their NMR spectroscopy.

The powerpoint slides contain answers to some of the in-class exercises, so those are behind the "faculty only" wall. I shares 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.

Building Molecular Orbitals for a Square Pyramidal Oxorhenium(V) Complex

Submitted by M. Watzky / University of Northern Colorado on Thu, 06/30/2016 - 17:21
Description

This activity guides students into building a Molecular Orbital diagram, which focuses on metal-centered orbitals of mostly d character, for a square pyramidal complex that includes different types of ligands. Students are then asked to "fill" the resulting orbitals with metal d electrons, and examine the stability of the complex.

Online Homework for a Foundations of Inorganic Chemistry Course

Submitted by Sabrina Sobel / Hofstra University on Mon, 06/27/2016 - 18:08
Description

The Committee on Professional Training (CPT) has restructured accreditation of Chemistry-related degrees, removing the old model of one year each of General, Analytical, Organic, and Physical Chemistry plus other relevant advanced classes as designed by the individual department. The new model (2008) requires one semester each in the five Foundation areas: Analytical, Inorganic, Organic, Biochemistry and Physical Chemistry, leaving General Chemistry as an option, with the development of advanced classes up to the individual departments.
