Terminal Iron–Dinitrogen and Iron–Imide Complexes Supported by a Tris(phosphino)borane Ligand (Peters)
Description

This literature discussion LO was created for the ACS National Award Winners 2026 collection for Dr. Jonas C. Peters, the recipient of the ACS Award in Inorganic Chemistry. This LO is based on the article "Terminal Iron–Dinitrogen and Iron–Imide Complexes Supported by a Tris(phosphino)borane Ligand" published in Angewandte Chemie Int. Eng.

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

Characterization of group VI carbonyls with bidentate phosphines
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.

Synthesis and Group Theory Analysis of MoO2(acac)2

Submitted by Amanda Reig / Ursinus College on Fri, 11/14/2025 - 12:27
Description

This laboratory experiment is a quick and straightforward synthesis of a MoO2(acac)2 complex. The ligand set allows for two possible geometric arrangements: cis and trans. Using IR spectroscopy along with group theory analysis of the Mo-O stretching modes, students can determine which isomer they formed in their synthesis. NMR spectroscopy is also employed, and confirms the geometric arrangement due to the inequivalence of the acac methyl groups.

1FLO: Addition of H2 to four-coordinate iridium
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

Submitted by Chip Nataro / Lafayette College on Wed, 10/08/2025 - 08:43

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.

Rhenium isocyanide complexes from the Figueroa group
Description

This literature discussion is in honor of Dr. Josh Figueroa, recipient of the 2026 F. Albert Cotton Award in Synthetic Inorganic Chemistry. Josh has done some tremendous work with isocyanide ligands and this paper is but a brief glimpse into this field. The complexes of interest contain carbonyl ligands and isocyanide ligands, so there are plenty of opportunities for students to use group theory to predict the number of IR-active vibrations for these ligands.

From Whiteboard to Spartan: An Integrated Exploration of H2A Molecular Orbitals and Molecular Geometry
Description

This two-part activity offers an integrated approach to understanding molecular orbitals and molecular geometry. In class, students will first engage in a hands on, qualitative construction of the H2O molecular orbital diagram using symmetry principles and a whiteboard.
