This is a great new textbook by George Luther III from the University of Delaware. The textbook represents the results of a course he has taught for graduate students in chemical oceanography, geochemistry and related disciplines. It is clear that the point of the book is to provide students with the core material from inorganic chemistry that they will need to explain inorganic processes in the environment.
The website shared here includes excellent simulations concerning a wide variety of techniques commonly used in materials science and inorganic chemistry. I have found it particularly useful for X-ray crystallography as the simulations help understand the lectures.
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
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.
The article “Synthesis and Reactivity of Oxorhenium(V) Methyl, Benzyl, and Phenyl Complexes with CO; Implications for a Unique Mechanism for Migratory Insertion,” Robbins, LK; Lilly, CP; Smeltz, JL; Boyle, PD; Ison, EA;, Organometallics 2015, 34, 3152-3158 is an interesting read for students studying reaction mechanisms of organometallic complexes. The reading guide directs students to the sections of the paper that support the question posed in the Discussion Questions document.
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.
Electron counting exercise motivated by a recent paper (J. Am. Chem.
This is an overview of some important principles of ligand design. Topics covered include HSAB theory, the chelate effect, the chelate ring size effect, the macrocyclic effect, the cryptate effect, and steric focus in ligand design.
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.
