Purchase of an X-Ray Diffraction Facility

X射线结晶学技术是测定小分子多肽和复杂金属簇合物分子结构的有力工具。当与最新的计算机软件相结合时，这项技术变得非常容易实施。使用X射线晶体仪器显著提高了化学家开展前沿研究的能力。范德比尔特大学化学系将利用化学仪器计划的这一奖项来帮助获得X射线衍射仪。收购将加强的化学研究领域如下：1)准备和研究新型超价物种的结构和反应活性2)具有反常光化学反应活性的桥烃配体双核化合物3)新型主族杂环的制备和结构测定4)有机电荷转移络合物及双功能有机分子中分子内电子转移的研究5)含空间大分子的Lewis酸性有机碱土化合物6)均相过渡金属烷基化合物的结构和反应活性。

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 the latest computer software, the technique is becoming remarkably easy to put into practice. Access to X-ray crystallographic instrumentation markedly improves the ability of chemists to carry out frontier research. The Department of Chemistry at Vanderbilt University will use this award from the Chemical Instrumentation Program to help acquire an X-ray diffractometer. The areas of chemical research that will be enhanced by the acquisition are as follows: 1) Preparation and study of the structure and reactivity of novel hypervalent species 2) Dinuclear compounds containing bridging hydrocarbon ligands with unusual photochemical reactivity 3) Preparation and structure determination of novel main-group heterocycles 4) Organic charge transfer complexes and the study of intramolecular electron transfer in bifunctional organic molecules 5) Lewis acidic Organoalkaline-earth compounds containing sterically bulky ligands 6) Structure and reactivity of homoleptic transition metal alkyl complexes.
