MRI: Acquisition of a Microfocus Single-Crystal Diffractometer

凭借主要研究仪器（MRI）和化学研究仪器和设施（CRIF）计划的这一奖项，牛津大学迈阿密大学将获得微焦点X射线衍射仪。一般来说，X射线衍射仪允许准确和精确地测量分子的完整三维结构，包括键距和角度，并提供关于分子相对于相邻分子的空间排列的准确信息。这里描述的研究将影响许多领域，包括有机和无机化学，材料化学和生物化学。该仪器将成为化学、生物化学和地质学研究生和本科生以及博士后研究员的教学以及研究和研究培训的一个组成部分，该奖项旨在加强各级研究和教育，特别是在以下领域：（a）使用三吡唑硼酸盐和三吡唑多甲烷作为配体整合高自旋钴系统的顺磁共振;（B）研究磷灰石中阳离子和阴离子固溶体的结构;（c）研究晶体生长过程中表面结构引起的不对称;（d）研究十钒酸盐;（e）制备具有复杂三维结构的大分子;（f）开发影响困难有机转化的催化方法;以及（g）将过渡金属和有机催化剂结合用于不对称有机转化。

With this award from the Major Research Instrumentation (MRI) and Chemistry Research Instrumentation and Facilities (CRIF) programs, Miami University at Oxford will acquire a microfocus X-ray diffractometer. In general, an X-ray diffractometer allows accurate and precise measurements of the full three-dimensional structure of a molecule, including bond distances and angles, and provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The studies described here will impact a number of areas, including organic and inorganic chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research and research training of chemistry, biochemistry and geology graduate and undergraduate students as well as postdoctoral fellows.The award is aimed at enhancing research and education at all levels, especially in areas such as (a) integrating paramagnetic resonance of high-spin cobalt systems using trispyrazolylborates and trispyrazolymethanes as ligands; (b) investigating the structure of cation and anion solid solutions in apatite; (c) studying surface structure induced dissymmetrization during crystal growth; (d) investigating decavanadates; (e) preparing large molecules with complex three-dimensional structures; (f) developing catalytic methods to affect difficult organic transformations; and (g) merging transition metal and organocatalysis for asymmetric organic transformations.
