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.

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购买一台带有 CCD 探测器的 X 射线衍射仪，用于小分子衍射分析。该设备将加强多个领域的研究：a）苯乙烯高效间同立构聚合催化剂体系的研究（Welch）； b) 配位聚膦酸酯的钙亲和力研究（Dikarev）； c) 硫、硒和硅的无环和杂环有机化合物的合成和研究，包括来自大蒜、洋葱和蘑菇的天然产物，以及硫化合物在有机合成中和作为配体的用途（块）； d）新型超分子材料的设计（Petrukhina）； e) 小球状蛋白折叠和展开的结构研究（Scholesz）； f) 含有甲硅烷基化和甲芽基化 β-二酮及相关辅助配体 (Toscano) 的金属配合物的合成、结构表征和物理化学评估。X 射线衍射仪可以精确测量分子的完整三维结构，包括键距离和角度，它提供了有关分子相对于相邻分子的空间排列的准确信息。 受益于该衍射仪的各种研究项目包括无机、有机金属、有机、材料、生物物理和生物有机化学领域的研究项目。
