STRUCTURAL INVESTIGATIONS OF ALKALI, ALKALINE EARTH AND RARE EARTH MATERIALS

点击翻译按钮获取中文摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. My group`s research interest lies in the synthesis and characterization of organometallic compounds involving the heavy alkali, alkaline earth and rare earth metals. These compounds are important as selective bases in synthetic application, as polymerization initiators, and, in select cases as precursor molecules for solid-state materials. This work is supported by the NSF. The target compounds are very reactive and need to be handled under strict inert gas conditions. Often, the crystals obtained are small and weakly diffracting. Their high reactivity does not allow extensive attempts of recrystallization. In many cases we collect data at 90K using our sealed tube CCD diffractometer, but in significant number of cases, the crystals obtained are too small to provide data of sufficient quality. We hope that using high intensity radiation, as provided at CHESS will provide the urgently needed structural information to allow for a meaningful structure function analysis
