This award is supported by the Major Research Instrumentation and the Chemistry Instrumentation Programs. Professor Banglin Chen from the University of Texas San Antonio and colleagues Michael Doyle and Zachary Tonzetich are acquiring a single crystal X-ray diffractometer equipped with a dual source of molybdenum and copper. In general, an X-ray diffractometer (XRD) allows accurate and precise measurements of the full three-dimensional structure of a molecule, including bond distances and angles. A diffractometer also provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The studies described here impact many areas, including organic and inorganic chemistry, materials chemistry and biochemistry. This instrument is an integral part of teaching as well as research and research training of undergraduate and graduate students in chemistry and biochemistry at this institution. The facility serves as a regional XRD resource benefitting students and faculty at Trinity University, St. Mary's University, and Incarnate Word University in San Antonio, as well as Texas Lutheran University, Texas A&M University-Kingsville, University of Texas at Rio Grande Valley, and Sul Ross State University in the greater South Texas region.The award of this diffractometer is aimed at enhancing research and education at all levels. It is especially useful for the characterization of synthetic crystal frameworks and during photophysical investigations of platinum(II) and iridium(III)-carbene complexes. The instrument also serves researchers developing and understanding homogeneous catalyst systems based on earth-abundant transition metals, and understanding the coordination geometries and chemical reactivities of model complexes of metalloproteins.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项由主要研究仪器和化学仪器项目支持。德克萨斯大学圣安东尼奥分校的陈邦林教授及其同事Michael Doyle和Zachary Tonzetich正在获得一台单晶X射线衍射仪，配备了钼和铜的双源。通常，X射线衍射仪(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，包括键距离和角度。衍射仪还提供关于分子相对于邻近分子的空间排列的准确信息。这里描述的研究影响到许多领域，包括有机化学和无机化学、材料化学和生物化学。该仪器是该机构化学和生物化学专业本科生和研究生教学、科研和培训不可或缺的一部分。该设施是一个地区性的X射线衍射仪资源，受益于圣安东尼奥的三一大学、圣玛丽大学和化身世界大学的学生和教职员工，以及德克萨斯路德大学、德克萨斯农工大学金斯维尔分校、里奥格兰德山谷的得克萨斯大学和南得克萨斯地区的南罗斯州立大学的学生和教职员工。它特别适用于合成晶体结构的表征以及铂(II)和Ir(III)-卡宾配合物的光物理研究。该仪器还帮助研究人员开发和了解基于富含地球的过渡金属的均相催化剂系统，并了解金属蛋白模型络合物的配位几何和化学反应活性。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
