Character Tables for Chemically Important Point Groups

Submitted by Chip Nataro / Lafayette College on Mon, 02/09/2026 - 19:04
Description

You might be familiar with the wonderful symmetry site that was (to my knowledge) originally published on the Jacobs University site and with the name change to the Constructor University site. In addition to having wonderful character tables, the site allowed you to enter reducible representations that the site would then reduce. It would also allow you to the full range of molecular motions or select vibrations (both IR and Raman active). The site has disappeared from time to time and it is unclear if it will ever return.

Si and Ge ferrocenes

Submitted by Chip Nataro / Lafayette College on Thu, 02/05/2026 - 17:12
Description

This literature discussion is in honor of the work of Shigeyoshi Inoue, winner of the 2026 Frederic Stanley Kipping Award in Silicon Chemistry for “groundbreaking contributions to the synthesis and reactivity of low-valent silicon compounds, and advancing the potential of silicon in metal-free catalysis and small-molecule activation” (https://cen.acs.org/a

Interactive Tanabe-Sugano diagram

Submitted by Patrick Holland / Yale University on Tue, 02/03/2026 - 21:35
Description

As a collaboration with Rajas Ketkar (an excellent student in my inorganic chemistry class), we now have an online tool that you can use to "pull" a vertical line across each Tanabe-Sugano diagram and read off the intersecting E/B values. This should make the process easier and more intuitive for students. Please credit Rajas when using in your classes!

Characterization of group VI carbonyls with bidentate phosphines

Submitted by Chip Nataro / Lafayette College on Thu, 01/15/2026 - 14:53
Description

This literature discussion comes from a paper in the Turkish Journal of Chemistry (199923, 9-14) https://journals.tubitak.gov.tr/chem/vol23/iss1/2/. In this paper, the authors report spectroscopic data for nine compounds, [M(CO)4(PP)] (M = Cr, Mo or W; PP = dppm, dppe, dppp). This is a very fundamental paper and as such, students are not expected to have had any significant coursework in inorganic chemistry.

Flavodiiron Oxygen Reductase

Submitted by Amanda Reig / Ursinus College on Thu, 11/20/2025 - 09:44
Description

This paper investigates factors that influence substrate specificity (O2 versus NO reductase activity) within flavodiiron enzymes. The authors mutate potentially relevant amino acids and investigate the biochemical and biophysical properties by UV-visible and EPR spectroscopies.

1FLO: Addition of H2 to four-coordinate iridium

Submitted by Chip Nataro / Lafayette College on Wed, 10/22/2025 - 13:41
Description

This paper (J. Organomet. Chem. 2022, 965-966, 122317) describes the synthesis and reactivity of four-coordinate iridium compound with a tridentate ligand. This ligand is referred to in the paper as a pincer ligand which are a general class of tridentate ligands that coordinate in a mer- arrangement.

2025 Nobel Prize in Chemistry - MOFs

In celebration of the 2025 Nobel prize in Chemistry awarded to Susumu Kitagawa, Richard Robson and Omar Yagi, this collection features various LOs about MOFs.

Metallocene cations and anions
Description

This is a really interesting paper in J. Am. Chem. Soc. (2025, 147, 34641-34646) involving a complex salt in which both the cation and anion are metallocenes. While a majority of the paper is focused on the characterization of two new compounds, it presents some excellent opportunities to practice counting electrons, one of which was a challenge to this author.
