Ionization-Structure-Reactivity Relationships in Transition Metal Chemistry: Metal-Metal Complexes

亚利桑那大学化学系的Dennis L.Lichtenberger博士在无机化学、生物无机化学和金属有机化学项目中的这一奖项为金属-金属相互作用的研究提供了持续的支持。所研究的体系包括四重和三重金属-金属键，金属-金属构型超过反键三角洲轨道的占据，以及非键和弱缔合的贯穿空间和贯穿配体的金属-金属相互作用。金属-金属络合物包含各种桥联和非桥联配体，并表现出与关键结构扰动相关的广泛的电子给予和电子撤出效应。还包括与轴向位置配位的弱配体和强配体的配合物。高分辨率的HeI/HeII价态和高精度的X射线核心光电子能谱将用于研究气相和凝聚物种。该项目包括进一步开发仪器能力。金属-金属相互作用影响着许多物种的结构、稳定性和反应活性，并影响重要的化学、催化和材料过程。将开发独特的仪器，以提供有关这些相互作用的详细电子结构信息

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program provides continued support for research on metal-metal interactions by Dr. Dennis L. Lichtenberger of the Chemistry Department, University of Arizona. Systems under investigation contain quadruple and triple metal-metal bonds, metal-metal configurations beyond occupation of the anti-bonding delta orbital, and non-bonding and weakly-associated through-space and through-ligand metal-metal interactions. The metal-metal complexes contain a variety of bridging and non-bridging ligands and represent a broad range of electron-donating and electron-withdrawing effects associated with key structural perturbations. Complexes with both weak and strong ligands coordinated to the axial position are also included. High-resolution HeI/HeII valence and high precision X-ray core photoelectron spectroscopy will be used to study both gas phase and condensed species. The project includes further development of instrumental capabilities. Metal-metal interactions contribute to the structure, stability, and reactivity of many species and influence important chemical, catalytic, and materials processes. Unique instrumentation will be developed to provide detailed electronic structure information on these interactions
