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

这个无机、生物无机和有机金属化学项目的奖项为亚利桑那大学化学系的Dennis L. Lichtenberger博士对金属-金属相互作用的研究提供了持续的支持。所研究的系统包含四重和三重金属-金属键，反键δ轨道之外的金属-金属构型，非键和弱相关的贯穿空间和贯穿配体金属-金属相互作用。金属-金属配合物包含多种桥接和非桥接配体，并表现出与关键结构扰动相关的广泛的给电子和吸电子效应。弱配体和强配体与轴位配位的配合物也包括在内。高分辨率HeI/HeII价和高精度x射线核心光电子能谱将用于气相和凝聚态的研究。该项目包括进一步发展仪器能力。金属-金属相互作用影响着许多物质的结构、稳定性和反应性，并影响着重要的化学、催化和材料过程。将开发独特的仪器来提供这些相互作用的详细电子结构信息
