This award in Inorganic, Bioinorganic, and Organometallic Chemistry supports research on metal-metal bonding in transition metal compounds by Dr. F. Albert Cotton, Chemistry Department, Texas A&M University. New dinuclear compounds with multiple metal bonds will be synthesized and structurally characterized. Of particular interest are compounds containing V, Nb, Ta, Fe and Mn, for which few examples of this bonding motif are known. The strategy is to synthesize ligands with binding sites that force the metals into the desired configuration. Emphasis will also be placed on compounds that have unusual oxidation states or structural features. In addition, species that contain chains of three or more metals atoms with conducting properties will be prepared. Compounds that contain two metal atoms linked together are of interest because of their unusual bonding behavior. They have been used as catalysts and for determining absolute configuration. In this study, the limits of metal-metal bonding will be tested with metals that have not exhibited this type of bonding previously. Compounds consisting of chains of metals are of interest in understanding metallic behavior and designing compounds with specific electronic properties.

该奖项在无机，生物无机和有机化学支持研究过渡金属化合物中的金属-金属键合的F。阿尔伯特·科顿，德克萨斯农工大学化学系。 新的双核化合物与多个金属键将被合成和结构表征。 特别令人感兴趣的是含有V、Nb、Ta、Fe和Mn的化合物，对于这些化合物，已知这种键合基序的例子很少。 该策略是合成具有结合位点的配体，该结合位点迫使金属成为所需的构型。 重点也将放在具有不寻常的氧化态或结构特征的化合物上。 此外，将制备含有具有导电性质的三个或更多个金属原子的链的物质。 含有两个金属原子连接在一起的化合物由于其不寻常的键合行为而引起人们的兴趣。 它们已被用作催化剂和用于确定绝对构型。 在这项研究中，金属-金属结合的极限将用以前没有表现出这种类型的结合的金属进行测试。 由金属链组成的化合物在理解金属行为和设计具有特定电子性质的化合物方面具有重要意义。
