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

Sheldon G. Shore博士，俄亥俄州立大学化学系，受化学系无机、生物无机和有机金属项目的支持，合成和研究形成扩展阵列的镧系过渡金属配合物，并研究金属配合物与新型硼烷配体的反应。将制备具有直接镧系过渡金属键的材料和一系列具有氰化物和氰酸盐桥接镧系过渡金属骨架的化合物。该计划的这一阶段旨在开发和扩展聚合物的合成途径，扩展阵列配合物将镧系元素和过渡金属结合到金属部分的一维，二维或三维排列中。其次，将研究镧系离子与新的硼烷阴离子的反应，这些硼烷阴离子与氮供体具有等电子，可以作为配体。该计划的这一方面将揭示硼烷化学的一个新方面和新型镧系硼烷的产率路线。镧系过渡金属配合物可以或可以作为电子、超导和磁性材料的前驱体。此外，还有许多具有重要商业价值的催化剂含有这两种金属。然而，同时含有镧系元素和过渡金属的配合物并不常见。该项目旨在扩大含有这些类型的金属的化合物的数量和类型，这些金属以独特的大型“阵列”相互连接，设计成逻辑形式，从中可以获得上述材料或催化剂。

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.
