Investigation of the Reactivity of Supraoctahedral Transition Metal Clusters

伊利诺伊州立大学化学系的启动补助金支持丽莎F教授的研究。什切普拉 研究的主题是调查的超八面体过渡金属簇的形式（M'M6X8）n（其中M'和M是过渡金属和X = S，Se，或Te），这是重要的理解集群反应的配体取代的机制。 特别是，旁观者配体上的配体交换率的影响将被检查。 第二个目标是研究超八面体团簇的氧化还原反应性。该项目中研究的团簇是一类称为Chevrel相材料的物质的一部分，即使在高磁场下也表现出超导性能。 然而，其它应用包括用作非均相催化剂和用作可再充电锂和锂离子电池中的阴极材料。 对这些类型的簇的研究对具有增加的循环寿命的新型锂电池的开发具有重大影响。

This starter grant award of the Chemistry Division to Illinois State University supports the research of Professor Lisa F. Szczepura. The theme of the research is the investigation of the mechanism of ligand substitution of supraoctahedral transition metal clusters of the form (M'M6X8)n (where M' and M are transition metals and X = S, Se, or Te) that are important for understanding cluster reactivity. In particular, the effects of spectator ligands on the rates of ligand exchange will be examined. A second goal is the study of the redox reactivity of supraoctahedral clusters.The clusters studied in this project are part of a class of substances called Chevrel phase materials, which exhibit superconducting properties even in high magnetic fields. However, other applications include use as heterogeneous catalysts and as cathode materials in rechargeable lithium and lithium ion batteries. Studies of these types of clusters have a significant impact on the development of new lithium batteries with increased cycle life.
