This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research by Gerard F. R. Parkin of the Department of Chemistry, Columbia University, on the synthesis of novel main group compounds. The s- and p-block compounds prepared will feature currently unknown functionalities, such as zinc complexes that bear terminal chalcogenido ligands and gallium complexes with terminal pnictide ligands. Molecules of this type are unknown and are of intrinsic fundamental interest in view of possible terminal-ligand to metal multiple bonding. The syntheses of these complexes will rely upon the use of ligands constructed so as to stabilize the functionalities under investigation. These include various tris-(pyrazolyl)borate and bis- and tris-(mercaptoimidazolyl)hydroborate ligands, C3-symmetric tridentate ligands based on a benzene platform, atranes ligands, terphenoxide ligands, and pyrrolyl ligands. Specific attention will be given to complexes that have novel structures but have a compositional relationship to the materials that have already found industrial applicationsThe main group elements have a variety of important applications in synthetic chemistry, solid state materials, and catalytic reactions. This project aims at understanding some of the unusual bonding and structural properties of some of the heavier members of the s- and p-block of the periodic table. Understanding of zinc and gallium bonding to terminal ligands may provide some insight into gas phase routes to materials. The project will involve undergraduate, graduate and postdoctoral students. The PI and his students will be involved in outreach to local schools.

该奖项在哥伦比亚大学化学系的Gerard F. R. Parkin的研究中支持了无机，生物无机和有机金属化学计划的研究，该研究是关于新型主要组化合物的合成的。制备的S-和P块化合物将具有目前未知的功能，例如锌配合物，这些锌配合物均带有末端的chalcogenido配体和带有末端PNICTIDE配体的镀铝配合物。这种类型的分子是未知的，鉴于可能的终端配体可能与金属多键合接头，并且具有内在的基本兴趣。这些复合物的合成将依赖于构造的配体的使用，以稳定所研究的功能。其中包括各种基于苯平台，阿特拉内斯配体，二氧化物氧化物配体，以及吡咯酚基体验的各种三（吡唑基）硼酸盐和双（辅助咪唑基）氢化体配体，c3对称三叉物三叉酸。将特别关注具有新颖结构但与已经发现工业应用的材料具有组成关系的复合物，主要组元素在合成化学，固态材料和催化反应中具有多种重要应用。该项目旨在了解周期表的S-和P块中一些重成员的某些异常粘合和结构特性。了解与末端配体的锌和凝胶键合可能可以提供一些对材料气相路线的见解。该项目将涉及本科生，研究生和博士后学生。 PI和他的学生将参与与当地学校的宣传。
