Dr. John P. Fackler of the Chemistry Department, Texas A&M University, is supported by the Inorganic, Bioinorganic, and Organometallic Program for investigation of the chemistry of dinuclear and polynuclear complexes of Group 11 elements, particularly copper and gold. Fackler will model metal-metal bond formation and rupture, as related to bimetallic oxidative addition reactions. The emphasis is on the influence of neighboring metals and coordinated ligands in gold complexes, but the results will have relevance to catalytic reactions of other d-10 metals, such as copper(I), silver(I), nickel, platinum and palladium. The luminescence properties of these compounds will be exploited for characterization. Mixed metal cluster systems involving copper(I) and silver(I) will also be studied, along with species containing platinum and gold chains. %%% In this basic research project, Dr. John Fackler of Texas A&M University will synthesize new compounds which contain two or more metal atoms. Gold will be used in most of these compounds, in combination with copper or silver. One compound, for example, that will be prepared will contain a chain of six gold and platinum atoms. The purpose of the study is to investigate the reactivity of the compounds in reactions in which small molecules, such as carbon monoxide and sulfur dioxide, are inserted into or across the metal-metal bond. These reactions serve as models for many types of catalytic reactions involving gold, platinum, palladium, silver, and nickel.

德克萨斯农工大学化学系的John P.Fackler博士得到了无机、生物无机和有机金属计划的支持，该计划用于研究第11族元素，特别是铜和金的双核和多核配合物的化学。Fackler将模拟与双金属氧化加成反应有关的金属-金属键的形成和断裂。重点讨论了金配合物中邻近金属和配位配体的影响，但结果对铜(I)、银(I)、镍、铂和钯等其他d-10金属的催化反应有一定的指导意义。这些化合物的发光性质将被用于表征。还将研究涉及铜(I)和银(I)的混合金属簇合物系统，以及含有铂和金链的物种。在这个基础研究项目中，德克萨斯农工大学的约翰·法克勒博士将合成含有两个或两个以上金属原子的新化合物。金将与铜或银结合在一起用于大多数这些化合物。例如，将制备的一种化合物将包含六个金和铂原子的链。这项研究的目的是研究化合物在小分子(如一氧化碳和二氧化硫)插入金属-金属键或穿过金属键的反应中的反应性。这些反应是金、铂、钯、银和镍等多种催化反应的模型。
