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

该职业奖在无机、生物无机和有机金属项目中支持由伊利诺伊州立大学Gregory M. Ferrence教授开展的涉及稀土配合物的研究和教育活动。本研究的一个目标是修改3族和镧系金属的支持配体环境，以便深入了解化学结构和反应性，这与稀土化合物在其主要的三价氧化态是不同的。稀土配合物与n -杂化卟啉和碳卟啉配体将被制备，预计将显示出与传统卟啉类似物不同的反应性。二价镧系配合物也将通过使用三吡唑硼酸盐配体进行研究，以便对二价镧系的化学性质有一个基本的了解。本提案的教育部分侧重于x射线晶体学的教学原理和实践，通过使用广泛的基于计算机的课程材料，使学生能够更好地根据三维可视化来确定分子的各个方面。区域文理学院和大学的教师和学生将参与其中，以便通过远程教育提供x射线课程的各个方面，并促进区域研究合作。

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.
