EXAFS分析表明，非晶态材料MoS3、WS3和WSe3的锂化导致凝聚成更大的金属团簇，这可能与Chevrel相结构中的团簇相似。这一结果与以前在分子簇化学中观察到的化学趋势是一致的。这些锂化物质代表了小分子团簇和固态之间独特的过渡区域，它们在创建大的金属硫化物团簇方面可能具有合成价值。X射线吸收测量是在斯坦福大学同步辐射实验室(SSRL)进行的，该实验室由基础能源科学办公室能源部支持。这项工作是在拉斯作为NIH博士后研究员在斯坦福大学时进行的。KOH下的XAS工作得到了NSF和NIH的支持。
EXAFS analysis has shown that lithiation of the amorphous materials MoS3, WS3, and WSe3 results in a condensation into larger metal cluster, which may be similar to the clustersfound in Chevrel-phase structures. This result is consistent with chemical trends previously observed in molecular cluster chemistry. These lithiated materialsrepresent a unique transition region between small molecular clusters and the solid state, and they may be of synthetic value in the creation of large metal-chalcogenide clusters.Acknowledgment.
