The technique of X-ray crystallography is a powerful tool for the determination of the molecular structure of compounds as diverse as small polypeptides and complex metal clusters. When combined with modern computing hardware and software, the technique is remarkably efficient to put into practice. The acquisition of X-ray crystallographic instrumentation markedly improves the ability of chemists to carry out frontier research. The Department of Chemistry at the University of Minnesota will use this award from the Chemistry Shared Instrumentation Program to help acquire, operate and maintain important upgrades for its current X-ray facility. The new instrumentation will be used to enhance research in the following areas of chemistry: 1) Crystallographic evidence for nucleophilic attack on nitriles 2) Hydrogen bonding patterns in solid state organic molecules 3) Structures of new organic and organometallic compounds 4) Structures of new transition metal carbonyl clusters 5) Synthesis and reactivity of gold transition metal alloy compounds with applications as catalysts and new materials.

X射线晶体学的技术是确定化合物的分子结构的强大工具，如小多肽和复杂的金属簇。 当与现代计算硬件和软件结合使用时，该技术非常有效地付诸实践。 X射线晶体学仪器的采集显着提高了化学家进行边境研究的能力。 明尼苏达大学化学系将使用化学共享仪器计划中的这一奖项，以帮助获取，操作和维护其当前X射线设施的重要升级。 新仪器将用于增强化学的以下领域的研究：1）对硝化物的亲核攻击的晶体学证据2）固态有机分子中的氢键模式3）新的有机和有机金属化合物的结构4）新型金属碳纤维的结构5）与新材料的构成材料相对于新材料的新材料和新材料的反应性相对于新材料构成了新材料。
