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

单晶和粉末X射线晶体学是用于确定固体的最强大的分析方法。 在合成的无机，有机，生物有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，而粉末衍射决定了纯度。 从分子间组成和结构的知识中获得的信息有助于发展对催化或有机合成的潜在普遍兴趣的新反应。 化学共享仪器计划的奖项将帮助爱荷华州立大学的化学系获得单晶X射线衍射仪和粉末衍射系统。 在获取的化学研究领域中，有以下内容：l。 金属金属键簇，链和薄板系统的固态化学2。二元和三元阶段的高温固态化学3。碳化物，金属和非金属的碳化物，硝酸盐和氧化物的前体4.超薄混合金属氧化物膜结构5。生物有机和生物有机化学
