Harnessing Ligand Coordination Chemistry for Stable Metal Complexes

Discover how triazole ligands enhance metal complex stability through proper steric shielding, illustrated with the NiCl model. Grinding solids in a mortar and pestle plays a key role in this research endeavor. Engaged in collaborative STEM work, A. Hofer expresses gratitude for the valuable experiences shared during the research period.

  1. Anthony K. Hofer, Jr., (Prof. G. M. Ferrence) www.ilstu.edu/~gferren Pyrazole and Triazole Hydridotris Ligands Attaching to Metal Complexes “I am both happy and thankful to have had the opportunity to work with the rest of the STEM fellows this summer and share experiences with them. They are great group of people, and good friends to keep in touch with after research is over for the summer” -A. Hofer At right is shown: A model of the molecule of interest (Ttztbu,me NiCl) The reaction of triazole compounds with a potassium borohydride molecule to form a tris ligand makes way for interesting coordination chemistry when this ligand as a whole is added onto a metal complex. With a sterically bulky ligand, like 3-tert-butyl-5-methyl-1,2,4-triazole, ample shielding around the metal atom in the complex is provided and thus makes way for a more stable molecule. In the case of the molecule pictured, the metal atom is nickel. Without proper steric shielding, this nickel is more apt to take part in chemical reactions with other molecules and shorten the lifespan of the entire molecule. Grinding solids in a mortar and pestle often played a large role in my research, as I am seen doing so here.
