2013 TRiO McNair Summer Research Internship-"Tuning Single-ion Anisotropy in Molecular Ni(II) Coordination Complexes Containing Imidazole and Pyrazole Analogs"
While some structural data exists for Ni(II) molecular coordination complexes containing halide anions and organic ligands, the literature tends to be outdated and systematic studies using chemical tunability have not been performed, often leaving out complexes containing the less commonly utilized members of the halide family, Fluoride and Iodide. Synthesis of these compounds has been carried out using Ni(II) coordinated to 2 halides and 4 organic ligands where the Halide is F,Cl,Br,I and the ligand can be a variety of organic molecules such as imidazole, benzimidazole, pyrazole or 4-methyl-1H-pyrazole. The goal is to create high quality singular crystals which can then undergo various instrumental testing. Once synthesized, these molecular complexes have an advantage over polymers in that they provide us with the unique opportunity to study the single-ion anisotropy (J) of the system while minimizing the interference of exchange interactions (J). Pulsed field data, electron resonance spectroscopy and x-ray data can provide additional insight into magnetic and structural properties of these materials and allow for a comparison of theoretical models to experimental data.
