Application of advanced instrumental and preparative techniques to the study of structure, reactivity, and spectroscopy of inorganic and organic substances including materials. This is a capstone course and includes a course-based undergraduate research experience (CURE) that runs throughout the semester.

This activity allows students to manipulate highly symmetric objects and find the symmetry elements that are present. 

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.

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.

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.

This literature discussion was prepared as part of the 2025 ACS awards collection in honor of Gary J. Schrobilgen, winner of the M. Frederick Hawthorne Award in Main Group Inorganic Chemistry.
