Acquisition of a Single-Crystal X-Ray Diffractometer with a CCD Area Detector and a High-Quality Optical Microscope

在化学研究仪器和设施-多用户仪器获取(CRIF-MU)计划的支持下，圣母大学化学系将购买一台具有CCD探测功能的单晶X射线衍射仪和一台光学显微镜。这项收购将使一系列研究项目成为可能，包括a)负氧化态的主族金属和半金属；b)低电子金属硼烷；c)在超分子合成中作为合成子的S嵌段金属聚集体；d)金属卟啉配合物的合成和表征；e)超分子化学；以及f)聚酮天然产物中的构象-活性关系。一名训练有素的结晶师将负责培训新用户，该设备将用于研究生水平的课程。此外，学校非常努力地招收和留住少数族裔学生，麦克奈尔项目每年夏天都会把大约30名少数族裔本科生带到校园来。X射线衍射仪可以精确和精确地测量分子的全部三维结构，包括键的距离和角度，并提供关于分子相对于邻近分子的空间排列的准确信息。这些研究将对材料化学产生重大影响。

With support from the Chemistry Research Instrumentation and Facilities - Multiuser Instrument Acquisition (CRIF-MU) Program, the Department of Chemistry at the University of Notre Dame will purchase a single-crystal X-ray diffractometer with CCD detection and an optical microscope. This acquisition would enable a number of research projects, including studies on a) main-group metals and semimetals in negative oxidation states; b) hypoelectronic metallaboranes; c) s-block metal aggregates as synthons in supramolecular synthesis; d) the synthesis and characterization of metalloporphyrin complexes; e) supramolecular chemistry; and f) comformation-activity relationships in polyketide natural products. A trained crystallographer will be responsible for training new users and that the equipment will be used in a graduate level course. In addition, there is a very strong effort to recruit and retain minority students and the McNair program brings roughly 30 minority undergraduates to campus each summer. The X-ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and it provides accurate information about the spatial arrangement of the molecule relative to the neighboring molecules. These studies will have a strong impact in materials chemistry.
