Acquisition of CCD-Based X-Ray Diffractometer

在化学研究仪器和设施（CRIF）计划的支持下，纽约州立大学奥尔巴尼分校化学系将获得一台带有CCD检测器的X射线衍射仪，用于小分子衍射。这一设备将加强若干领域的研究：a）研究苯乙烯有效间规聚合的催化剂系统（Welch）; B）研究配位聚膦酸酯的钙亲和性（Dikarev）; c）合成和研究硫、硒和硅的非环状和杂环有机化合物，包括大蒜、洋葱和蘑菇的天然产物，以及硫化合物在有机合成中的应用和作为配体（Block）; d）新型超分子材料的设计（Petrukhina）; e）小球状蛋白质折叠和展开的结构研究（斯科尔斯）;和f）合成，含甲硅烷基化和锗化β-X射线衍射仪允许精确和精确地测量分子的完整三维结构，包括键距和角度，并且它提供关于分子相对于相邻分子的空间排列的准确信息。 将受益于该衍射仪的各种研究计划包括无机，有机金属，有机，材料，生物物理和生物有机化学。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at SUNY Albany will acquire an X-ray diffractometer with CCD detector for small molecule diffractometry. This equipment will enhance research in a number of areas: a) investigations of catalyst systems for efficient syndiotactic polymerization of styrene (Welch); b) studies on the calcium affinity of coordinated polyphosphonates (Dikarev); c) synthesis and study of acyclic and heterocyclic organic compounds of sulfur, selenium and silicon, including natural products from garlic, onions, and mushrooms, and the use of sulfur compounds in organic synthesis and as ligands (Block); d) design of novel supramolecular materials (Petrukhina); e) structural studies on the folding and unfolding of small globular proteins (Scholesz); and f) synthesis, structural characterization and physicochemical evaluation of metal complexes containing silylated and germylated beta-diketonates and related ancillary ligands (Toscano).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. The diverse research programs that will benefit from this diffractometer include those in inorganic, organometallic, organic, materials, biophysical and bioorganic chemistry.
