Upgrade of the Departmental X-Ray Diffractometer

X 射线晶体学技术是确定小多肽和复杂金属簇等多种化合物分子结构的有力工具。 当与现代计算硬件和软件相结合时，该技术的实施效率非常高。 X射线晶体学仪器的购置，显着提高了化学家开展前沿研究的能力。 明尼苏达大学化学系将利用化学共享仪器计划的这一奖项来帮助其当前 X 射线设施的获取、操作和维护重要升级。 新仪器将用于加强以下化学领域的研究：1）腈类亲核攻击的晶体学证据2）固态有机分子中的氢键模式3）新型有机和有机金属化合物的结构4）新型过渡金属羰基簇的结构5）金过渡金属合金化合物的合成和反应性及其作为催化剂和新材料的应用。

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.
