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的化学系将获得一台带有CCD探测器的X射线衍射仪，用于小分子衍射仪。该设备将加强下列领域的研究：a)研究高效间规聚合的催化剂体系(韦尔奇)；b)配位多膦酸盐的钙亲和力研究(Dikarev)；c)硫、硒和硅的非环和杂环有机化合物的合成和研究，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)；和f)含有硅化和胚化的β-二酮及其相关辅助配体的金属络合物(Toscano)的合成、结构表征和物理化学评价。X射线衍射仪可以准确和精确地测量分子的全部三维结构，包括键长和键角，并提供关于分子相对于邻近分子的空间排列的准确信息。将受益于该衍射仪的不同研究项目包括无机、有机金属、有机、材料、生物物理和生物有机化学。
