With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Texas A&M University will acquire an X-ray powder diffractometer. This equipment will enhance research in a number of areas including the following: a) metal phosphonate chemistry; b) synthesis, structure and ion exchange behavior of inorganic ion exchange materials; c) micro- and mesoporous materials made from polymetal components; d) design, synthesis and magneto-structural correlation of molecule-based magnets; e) introduction of bidentate Lewis acidic functionalities in microporous solids; and f) synthesis of hybrid materials and products of ion-exchange reactions.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, especially materials science.

在主要研究仪器(MRI)计划的支持下，德克萨斯农工大学化学系将获得一台X射线粉末衍射仪。该设备将加强以下领域的研究：a)金属膦酸盐化学；b)无机离子交换材料的合成、结构和离子交换行为；c)由多金属组分制成的微孔和介孔材料；d)分子基磁体的设计、合成和磁结构相关性；e)在微孔固体中引入双齿Lewis酸性官能团；和f)杂化材料和离子交换反应产物的合成。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，特别是材料科学。
