Purchase of Single Crystal and Powder X-Ray Diffractometers

单晶和粉末x射线晶体学是测定固体结构最有效的分析方法。在合成无机、有机、生物无机和有机金属化学中，单晶x射线衍射是表征分子结构的宝贵工具，而粉末衍射决定纯度。从分子间组成和结构的知识中获得的信息有助于开发催化或有机合成中潜在的普遍感兴趣的新反应。这份来自化学共享仪器项目的资助将帮助爱荷华州立大学化学系获得单晶x射线衍射仪和粉末衍射系统。此次收购将加强的化学研究领域包括：1 .金属-金属键簇、键链和键片体系的固态化学二相和三元相的高温固体化学金属和非金属的碳化物、氮化物和氧化物的前体超薄混合金属氧化物膜结构有机元素化学，其中元素是硅、锗、锡、磷、砷、汞或过渡金属。生物无机化学和生物有机化学

Single crystal and powder X-ray crystallography is the most powerful analytical method for structure determination of solids. In synthetic inorganic, organic, bioinorganic and organometallic chemistry, single crystal X-ray diffraction is an invaluable tool to characterize molecular structure, whereas powder diffraction determines purity. The information gained from the knowledge of the intermolecular composition and structure helps to develop new reactions of potentially general interest in catalysis or organic synthesis. This award from the Chemistry Shared Instrumentation Program will help the Department of Chemistry at the Iowa State University acquire a single-crystal X-ray diffractometer and a powder diffraction system. Among the areas of chemical research that will be enhanced by the acquisition are the following: l. Solid state chemistry of metal-metal bonded cluster, chain and sheet systems 2. High-temperature solid state chemistry of binary and ternary phases 3. Precursors to carbides, nitrides and oxides of metals and nonmetals 4. Ultra-thin mixed metal oxide film structures 5. Organo-element chemistry where the element is silicon, germanium, tin, phosphorus, arsenic, mercury or a transition metal 6. Bioinorganic and bioorganic chemistry
