Synthesis and Studies of Lanthanide-Transition Metal Complexes (Extended Arrays); Reactions of Metal Complexes with New Borane Ligands

谢尔顿·肖尔博士，俄亥俄州立大学化学系，由化学部无机、生物无机和有机金属计划支持，合成和研究形成扩展阵列的稀土过渡金属络合物，并研究金属络合物与新的硼烷配体的反应。将制备具有直接稀土过渡金属键的材料和一系列具有氰化物和氰酸盐桥联的稀土过渡金属骨架的化合物。该计划的这一阶段旨在开发和扩大合成聚合物、扩展阵列络合物的途径，这些络合物将镧系元素和过渡金属纳入一维、二维或三维金属部分的排列中。其次，将考察稀土离子与新的与氮给体等电子的、可作为配体的硼烷阴离子的反应。该计划的这一方面将揭示硼烷化学的一个新方面，并获得新型镧系元素硼烷的路线。稀土过渡金属络合物可以或可以作为电子、超导和磁性材料的前驱物质。此外，还有一些具有重要商业价值的催化剂，它们都含有这两种金属。然而，同时含有稀土和过渡金属的络合物并不常见。该项目旨在扩大包含这些类型的金属的化合物的数量和类型，使其以独特的大阵列形式相互连接，设计成可从其中获得上述材料或催化剂的逻辑形式。

Dr. Sheldon G. Shore, Department of Chemistry, Ohio State University, is supported by the Inorganic, Bioinorganic, and Organometallic Program of the Chemistry Division to synthesize and study lanthanide-transition metal complexes that form extended arrays and for the study of the reactions of metal complexes with new borane ligands. Materials that have direct lanthanide transition metal bonds and a series of compounds with cyanide and cyanate bridged lanthanide-transition metal backbones will be prepared. This phase of the program is designed to develop and expand avenues for the synthesis of polymeric, extended array complexes that incorporate both lanthanide and transition metals into a one, two, or three dimensional arrangement of metal moieties. Secondly, the reactions of lanthanide ions with new borane anions that are isoelectronic with nitrogen donors and that can function as ligands will be examined. This aspect of the program will uncover a new aspect of borane chemistry and yield routes to new types of lanthanide boranes. Lanthanide-transition metal complexes can be or can serve as precusors to electronic, superconducting, and magnetic materials. In addition there are a number of commercially important catalysts that contain both types of metals. Nonetheless, complexes containing both lanthanide and transition metals are not common. This project aims at extending the number and types of compounds that contain these types of metals joined to each other in unique large `arrays,` designed to be logical forms from which the materials or catalysts mentioned above may be obtained.
