With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at City University of New York/Hunter College will acquire a X-ray diffractometer with CCD detector for small molecule diffractometry. This equipment will enhance research in a number of areas including the following: a) self-assembly of nano-scaled, solid-state photonic materials; b) lanthanide polyoxometalates: building blocks for new materials; c) polyoxometalate anions and metalloenzyme mimics; d) redox-mediated chiroptical materials; e) synthetic carbohydrate chemistry; f) chiral phosphorus ligands and antisense oligonucleotides; g) complexes formed by bile acids, cholesterol and other steroids with cyclodextrin derivatives and synthetic receptors; h) quantum crystallography of molecules; and i) study of geometry and electronic environment of metal sites by solid state NMR and X-ray crystallography.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. These studies will have an impact in a number of areas, including materials chemistry and biochemistry.

在主要研究仪器(MRI)计划的支持下，纽约城市大学/亨特学院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。该设备将加强以下领域的研究：a)纳米级固态光子材料的自组装；b)稀土多金属氧酸盐：新材料的构建块；c)多金属氧酸盐阴离子和金属酶模拟物；d)氧化还原介导的手性材料；e)合成碳水化合物化学；f)手性磷配体和反义寡核苷酸；g)胆汁酸、胆固醇和其他类固醇与环糊精衍生物和合成受体形成的络合物；h)分子的量子晶体学；和i)用固体核磁共振和X射线结晶学研究金属位置的几何和电子环境。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，包括键距离和角度，并提供关于分子相对于邻近分子的空间排列的准确信息。这些研究将在多个领域产生影响，包括材料化学和生物化学。
