Extended Metal-Metal Interactions: d8 Stabilized Multiply Bonded Dimers and Oligomeric Pt-Bipyridine Springs

内华达大学雷诺分校化学系文森特·卡塔拉诺博士获得了化学系无机、生物无机和有机金属项目的支持，该项目获得了学院早期职业发展奖，以表彰对金属-金属相互作用的扩展研究。多金属配合物将通过双齿或多齿配体将多键金属-金属二聚体桥联到后过渡金属配合物上来制备。我们将探索这些体系与二氧化碳等小分子的反应能力。此外，还将通过烯烃键将多个联吡啶共价连接起来，制备螺旋形的铂-联吡啶配合物。这些络合物有可能作为蒸气、气压或溶剂-显色传感器。该教育计划旨在通过简单的计划，提高各级教育的科学素养，这些计划可以在“全球思考--本地化行动”的基础上实施，其中包括将化学概念与热点问题联系起来，将教学与研究结合起来，以及通过化学俱乐部和科学博览会活动进行公众宣传。将设计合成系统，其中金属原子可以在扩展的线性网络中相互作用。由于广泛的金属-金属相互作用，这些体系有望在其反应性和物理性质上独一无二。从理解金属-金属成键和整个空间相互作用的角度来看，它们具有根本的意义，它们可能在传感器和小分子激活方面有应用。教育计划的重点是修改传统的化学课程，将专题问题包括在内，并将教学与研究结合起来。

Dr. Vincent Catalano, Department of Chemistry, University of Nevada, Reno, is supported by the Inorganic, Bioinorganic, and Organometallic Program of the Chemistry Division under a Faculty Early Career Development Award for studies of extended metal-metal interactions. Multi-metallic complexes will be prepared by bridging multiply bonded metal-metal dimers to late transition metal complexes using bidentate or multidentate ligands. The reactivity of these systems with small molecules such as carbon dioxide will be explored. Also, helical shaped platinum bipyridine complexes will be prepared by covalently linking multiple bipyridines through alkene linkages. These complexes have the potential to act as vapo-, baro-, or solvato-chromic sensors. The educational plan is aimed at increasing science literacy at all levels of education through simple programs that can be implemented based on a `think globally-act locally` approach, which includes tying chemical concepts to topical issues, integration of teaching with research, and public outreach through chemistry club and science fair activities. Synthetic systems will be designed in which metal atoms can interact with one another in extended linear networks. These systems are expected to be unique in their reactivity and in their physical properties due to the extended metal-metal interactions. They are of fundamental interest from the standpoint of understanding metal-metal bonding and through-space interactions, and they may have applications as sensors and in small molecule activation. The educational plan focuses on modifications of traditional chemistry courses to include topical issues and to integrate teaching with research.
