John N. Huffman, CAVE Facility Systems Administrator and Research Programmer, Indiana University Bloomington, examines the structure of a molecule of diethylaluminumtristetrabutylpyrazolylborate (Inorg. Chem. 1996, 35, 445-450). The compound, which is a potential catalyst for creating specialized polymers, was synthesized by Nancy Eilerts (currently at Phillips Research Center, Phillips Petroleum Company, Bartlesville, Oklahoma) working as a postdoctoral fellow under the direction of Malcolm H. Chisholm, Distinguished Professor of Chemistry, IUB. The structure was determined by John C. Huffman, Senior Scientist in Chemistry and director of the IU Molecular Structure Center.
