This poster displays the five ligands we examined in our experiment ranked in order of how well they stabilized an (SNO)- ligand, and a summary of our main findings.

Description:

Our objective was to find a ligand that best stabilized an (SNO)- ligand coordinated to an iron center upon computational modeling. Computational optimizations included those for geometry, vibrational spectroscopy, UV-Visible spectroscopy, and molecular orbitals.

Using Fe-O bond length as a proxy to track stability, we discovered that a ligand with a 1) high degree of aromaticity and 2) pi-accepting character was best for stabilizing (SNO)-.

I hadn’t really heard about CURE until taking this class. I appreciate the way CURE challenged me and I think CURE has increased my confidence about participating in research at Brown. It was a different experience from the typical lab portions of the class. I think there are advantages and disadvantages, it was unique and interesting and taught team building.
