This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at North Carolina State University in the purchase of a modern single- crystal diffraction system. This new instrumentation will enhance greatly research in a number of areas, including the following: (1) Organosulfur Complexes as Highly Conducting Materials; (2) Synthesis of Natural Products and Biologically Active Compounds Via Homochiral N-Acylpyridinium Salts; (3) Synthesis, Structure and Reactivity of Vanadium- Protein Model Systems; (4) Stereocontrolled Nucleophilic Addition Reactions to Acyclic Acetals; (5) Metal Halides at the Interface of Molecular and Solid State Chemistry; and (6) Synthesis and Characterization of Organic-Based Magnetic Materials. The X-ray diffractometer is used to make accurate and precise measurements of the full three- dimensional structure of a molecule. The information obtained gives the precise values of all the bond distances and bond angles of a given molecule and it gives accurate information about the spatial arrangement of that molecule relative to the neighboring molecules.

化学研究仪器和设施项目的这一奖项将帮助北卡罗来纳州立大学化学系购买现代单晶衍射系统。这一新的仪器将大大加强以下领域的研究：(1)有机硫配合物作为高导电材料；(2)通过高手性N-酰基吡啶盐合成天然产物和生物活性化合物；(3)钒-蛋白质模型体系的合成、结构和反应活性；(4)无环缩醛的立体控制亲核加成反应；(5)分子和固体化学界面上的金属卤化物；以及(6)有机基磁性材料的合成和表征。X射线衍射仪被用来对分子的全部三维结构进行精确和精确的测量。得到的信息给出了给定分子的所有键距和键角的精确值，并提供了关于该分子相对于邻近分子的空间排列的准确信息。
