Investigation of the Reactivity of Supraoctahedral Transition Metal Clusters

伊利诺伊州立大学化学系的启动基金资助了Lisa F. Szczepura教授的研究。本研究的主题是研究（M‘ m6x8）n（其中M’和M是过渡金属，X = S， Se或Te）形式的超八面体过渡金属簇的配体取代机制，这对理解簇的反应性很重要。特别地，观察配体对配体交换速率的影响将被检查。第二个目标是研究超八面体簇的氧化还原反应性。在这个项目中研究的簇是一类被称为Chevrel相材料的物质的一部分，即使在高磁场中也表现出超导特性。然而，其他应用包括用作多相催化剂和可充电锂电池和锂离子电池的正极材料。这类簇的研究对提高循环寿命的新型锂电池的开发具有重要的影响。

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.
