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.

x射线晶体学技术是测定小多肽和复杂金属团簇等多种化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。x射线晶体仪器的使用大大提高了化学家进行前沿研究的能力。范德比尔特大学化学系将利用化学仪器计划的这笔奖金来帮助获得一台x射线衍射仪。此次收购将加强的化学研究领域如下：1)新型高价物质的制备与结构与反应性研究2)具有特殊光化学反应性的桥接碳氢配体双核化合物3)制备与结构新型主基杂环的测定4)有机电荷转移配合物及双功能有机分子中分子内电子转移的研究5)含立体体积配体的路易斯酸性有机碱土化合物6)同色过渡金属烷基配合物的结构与反应性。
