Purchase of X-Ray Diffractometer

在化学研究仪器和设施（CRIF）项目的支持下，位于里诺的内华达大学化学系将升级一台带有小分子晶体学区域探测器的x射线衍射仪。该设备将加强若干领域的研究，包括：a)研究大型笼状配合物（称为金属隐式配合物）中的金属-金属相互作用，探测简单三角配位铂和钯膦配合物与重金属离子之间的亲金属相互作用；B)开发用于水相或双相有机金属催化的配体；C)以带状和螺旋结构为主的苯甲酸甲酯纳米结构的合成与表征；D)定向合成短纳米管和包括富勒烯在内的全氟碳基材料；E)低聚吡咯中氢键的研究；F)金属促进合成的研究；G)亲核试剂末端炔烃加成催化剂的研制；H)不对称合成手性膦烷和膦烯的金属模板的构建；(1)溶性致色中质结构-序-性质关系的研究。x射线衍射仪可以精确测量分子的完整三维结构，包括键的距离和角度，以及分子相对于邻近分子的空间排列。这些研究将在许多领域产生影响，包括材料化学和制备更有效的催化剂。此外，内华达大学里诺分校的研究生和本科生将有一个独特而重要的机会参与化学研究技术，许多人将在未来的工作中依赖。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Nevada in Reno will upgrade an X-ray diffractometer with an area detector for small molecule crystallography. This equipment will enhance research in a number of areas including the following: a) investigations of metal-metal interactions in large cage complexes known as metallocryptands, probing metallophilic interactions between simple trigonally coordinated platinum and palladium phosphine complexes and heavy metal ions; b) development of ligands for aqueous or biphasic organometallic catalysis; c) synthesis and characterization of benzoid nanostructures focused on ribbon and helical structures; d) directed synthesis of short nanotubes and perfluorinated carbon based materials including fullerenes; e) investigations of hydrogen bonding in oligopyrrole species; f) studies in metal promoted syntheses; g) development of catalysts for the addition of nucleophiles to terminal alkynes; h) construction of metal templates for the asymmetric synthesis of chiral phosphiranes and phosphirenes; and i) the investigation of structure-order-property relationships in lyotropic chromonic mesogens. The x -ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and the spatial arrangement of the molecule relative to the neighboring molecules. These studies will have an impact in a number of areas, including materials chemistry and the preparation of more efficient catalysts. In addition, graduate and undergraduate students at the University of Nevada in Reno will have a unique and important opportunity to participate in a chemical research technique that many will depend upon in their future jobs.
