This NSF Young Investigator award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research on metal silicides by Dr. Ziling B. Xue of the Chemistry Department, University of Tennessee at Knoxville. Two areas are emphasized: development of synthetic routes to metal silicides and polysilanes, and investigation of the mechanism of solid state organometallic reactions. On the first topic, early transition metal silyl complexes which do not contain cyclopentadiene or analogous ligands will be prepared; very few compounds of this type are known. These compounds will be used to develop a new route to metal silicides and polysilanes, which are useful for electronic devices. Tetrahydrosilane will also be used to form metal silicides under chemical vapor deposition conditions. In the second area, solid-gas reactions of alkyl compounds with phosphines will be studied. Research will focus on the factors affecting retention of solid state structure during reaction. Instrumentation from Oak Ridge National Laboratory will be used for some of the structural determinations. This work has implications for synthesis of heterogeneous catalysts.

这项 NSF 无机、生物无机和有机金属化学项目青年研究员奖支持田纳西大学诺克斯维尔分校化学系的 Ziling B. Xu 博士对金属硅化物的研究。 重点研究两个领域：金属硅化物和聚硅烷的合成路线的开发以及固态有机金属反应机理的研究。 第一个课题是制备不含环戊二烯或类似配体的早期过渡金属甲硅烷基配合物；已知的此类化合物很少。 这些化合物将用于开发可用于电子设备的金属硅化物和聚硅烷的新途径。 四氢硅烷也将用于在化学气相沉积条件下形成金属硅化物。 在第二个领域，将研究烷基化合物与膦的固气反应。 研究将重点关注反应过程中影响固态结构保留的因素。 橡树岭国家实验室的仪器将用于一些结构测定。 这项工作对多相催化剂的合成具有重要意义。
