9309690 Barton This award from the Chemistry Research Instrumentation Program will assist the Department of Chemistry at the University of Missouri--St. Louis in the purchase of an x-ray diffractometer and an associated data analysis system. This new instrumentation will enhance greatly research in a number of areas including the following: Structural and mechanistic studies of Dppc-bridged diplatinum complexes; Structural studies of group IV derivatives of pentaborane(9) and hexaborane(10); The use of high resolution diffraction x-ray analyses of the electronic and structural properties of organometallic molecules; Chiral phosphonamides in stereoselective bond formations; and Structural studies of silicon tricycles and silicon-silicon bonds. %%% The x-ray diffractometer is used to make accurate and precise measurements of the full three-dimensional structure of a molecule. The information obtained gives the precise values of all the bond distances and bond angles of a given molecule and it gives accurate information about the spatial arrangement of that molecule relative to the neighboring molecules. ***

9309690巴顿化学研究仪器项目的这一奖项将协助密苏里州-圣路易斯大学化学系购买X射线衍射仪和相关的数据分析系统。 这一新仪器将大大加强若干领域的研究，包括：Dppc-桥连双铂配合物的结构和机理研究;戊硼烷（9）和己硼烷（10）的IV族衍生物的结构研究;有机金属分子电子和结构性质的高分辨率X射线衍射分析的使用;立体选择性键形成中的手性膦酰胺;以及硅三环和硅-硅键的结构研究。 % X射线衍射仪用于精确测量分子的完整三维结构。 所获得的信息给出了给定分子的所有键距和键角的精确值，并且它给出了关于该分子相对于相邻分子的空间排列的准确信息。 ***
