This literature discussion comes from a paper in the Turkish Journal of Chemistry (1999, 23, 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.

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.

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.

This literature discussion was inspired by a talk given by Dr. Nora Radu, recipient of the 2025 ACS Award for Distinguished Service in the Advancement of Inorganic Chemistry. It is a bit 'big picture' in nature in that the hydrocyanation reaction is important for the synthesis of nylon. As such, there is a significant amount of background material relating to nylon-6,6. Students will read an article from C&EN, portions of a patent, and portions of an article from J. Chem.

This literature discussion is based on a short JACS communication reporting the first isolable Sc(II) carbonyls (not a typo) and isocyanides.  The paper discusses some standard synthesis and characterization while exploring a more fundamental question regarding why Sc, a d-block metal, is considered a rare-earth and when it stops reacting analogously to the rare-earth metals.  The LO focuses on ye olde carbonyl stretching frequencies and back-bonding and makes a nice follow up to an introduction to that concept.  It tries to make students explicitly connect electron configuration to changes

This literature discussion LO was created for the ACS National Award Winners 2025 collection. Dr. Greg C. Fu for being the recipient of the Gabor A. Somorjai Award for Creative Research in Catalysis 2025 from the American Chemical Society.
