"Synthesis of Low-Coordinate Main Group, d-Block, and F-Block Complexes"

One area of current interest involves the design, isolation and stabilization of main group, d-block, and f-block complexes with unusual bonding modes and oxidation states. This 10 week summer project is focused on the development of new sterically demanding ligand systems to support novel unsaturated and highly reactive metal compounds. From a fundamental structure/bonding viewpoint, the isolation of such complexes is essential if a comprehensive understanding is to be attained. Additionally, from a more applied perspective, we are also interested in the examination of the structure/activity relationships of low-coordinate and highly reactive metal centers with a goal of their exploitation in catalysis. REU students will utilize standard Schlenk line and glove box techniques for the manipulation of air-sensitive compounds. The characterization of new complexes typically includes single crystal X-ray diffraction, multinuclear NMR, FT-IR and UV/VIS spectroscopy, and DFT calculations.

These investigations, while rooted in traditional aspects of chemistry, will often involve students in collaborations with an array of other scientists and engineers. Group members have their own projects; however, each group member's research will have significant overlap with others in the group. As such, the students' depth of fundamental chemical principles will become augmented by exposure to a breadth of additional concepts. It is anticipated that such a combination of skills results in a fertile and created environment for achievement of research goals. Therefore, students should frequently expand beyond the reaches of classical chemistry subjects, and embrace additional areas, as required, for the successful execution of a specific project.
