项目摘要

This award by the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Professor Malcolm H. Chisholm at the Ohio State University to investigate two aspects of the dinuclear chemistry of molybdenum and tungsten: 1) The activation of multiple bonds in nitriles, alkynes and dinitrogen in their reactions with compounds having M-M multiple bonds, and 2) The preparation and characterization of linked dimers of dimers, cyclotetramers and mesogens containing M-M multiple bonds. Particular emphasis is given to establishing the kinetic and thermodynamic factors that control the metathesis reactions in which multiple bonds are exchanged between dinuclear complexes and those in nitriles, alkynes and dinitrogen. In the second project specific attention is given to dinuclear compounds with bridging carboxylate linkers. Single electron oxidized and reduced species will be prepared and examined by epr spectroscopy to evaluate the electron delocalization. The thermotropic mesophases of the dinuclear complexes doped with paramagnetic complexes will be studied by magnetic resonance in order to establish the alignment of the columnar phase and he localization or delocalization of the paramagnetic site. Complexes with two metal atoms will be investigated for their reactivity with small molecules with multiple bonds and for their ability to form novel supramolecules and materials.

This award by the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Professor Malcolm H. Chisholm at the Ohio State University to investigate two aspects of the dinuclear chemistry of molybdenum and tungsten: 1) The activation of multiple bonds in nitriles, alkynes and dinitrogen in their reactions with compounds having M-M multiple bonds, and 2) The preparation and characterization of连接的二聚体，含有M-M多键的二聚体，环渗透剂和中质二聚体。特别强调了建立控制分解反应的动力学和热力学因素，其中二核复合物与硝酸盐，炔烃和二氮的多个键交换。在第二个项目中，特别注意具有桥接羧酸盐接头的双核化合物。通过EPR光谱法制备并检查单一电子氧化和还原物种，以评估电子离域化。将通过磁共振来研究掺杂磁磁复合物的双核复合物的热中介，以建立柱状相位的比对，并将其定位或去磁性位点定位或定位。将研究具有两个金属原子的复合物，其与具有多个键的小分子的反应性以及它们形成新型超分子和材料的能力。
