项目摘要

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.

在化学研究仪器和设施-多用户仪器采购（CRIF-MU）计划的支持下，圣母大学化学系将购买一台带CCD检测的单晶X射线衍射仪和一台光学显微镜。这一收购将使一些研究项目成为可能，包括研究a）负氧化态的主族金属和半金属; B）次电子金属硼烷; c）在超分子合成中作为配体的s-区金属聚集体; d）金属卟啉络合物的合成和表征; e）超分子化学; f）聚酮化合物天然产物中的构象-活性关系。一名经过培训的晶体学家将负责培训新用户，该设备将用于研究生课程。此外，有一个非常强大的努力，以招募和留住少数民族学生和麦克奈尔计划带来了大约30个少数民族本科生到校园每年夏天。 X射线衍射仪可以精确测量分子的完整三维结构，包括键距和角度，并提供有关分子相对于相邻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。
