CAREER: Crystallography And Rare-Earth Educational and Research activities.

这一无机、生物无机和有机金属项目的职业奖项支持伊利诺伊州立大学格雷戈里·M·费伦斯教授关于稀土络合物的研究和教育活动。本研究的目的之一是修饰第三族金属和稀土金属的支持配体环境，以便深入了解稀土化合物的化学结构和反应活性，这些化学结构和反应活性有别于以三价氧化为主的稀土化合物。将制备具有N-混杂卟啉和碳卟啉配体的稀土络合物，与其传统的卟啉类似物相比，有望显示出对比的反应活性。二价稀土络合物也将通过使用三吡唑基硼配体进行研究，以提供对二价稀土化合物化学的基本了解。这项建议的教学部分侧重于通过使用广泛的基于计算机的课程材料来教授X射线结晶学的原理和实践，使学生能够更好地确定依赖于三维可视化的分子的各个方面。来自地区文科学院和大学的教职员工和学生将参与进来，通过远程教育提供X光课程的各个方面，并促进地区研究合作。

This CAREER award in the Inorganic, Bioinorganic, and Organometallic program supports research and educational activities involving rare-earth complexes by Professor Gregory M. Ferrence at Illinois State University. One goal of this research is to modify the supporting ligand environments of Group 3 and lanthanide metals in order to gain insight into chemical structure and reactivity that is distinct to rare-earth compounds in their predominant trivalent oxidation state. Rare earth complexes with N-confused-porphyrin and carbaporphyrin ligands will be prepared, which are expected to display contrasting reactivity compared to their traditional porphyrin analogs. Divalent lanthanide complexes will also be studied by using trispyrazolylborate ligands in order to also provide a fundamental understanding of the chemistry of divalent lanthanides.The educational component of this proposal focuses on teaching principles and practices in X-ray crystallography by using extensive computer based course materials that better enable students to determine aspects of molecules dependent on three dimensional visualizations. Faculty and students from regional liberal arts colleges and universities will be involved so as to offer aspects of the X-ray course via distance education and to foster regional research collaborations.
