This CAREER award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports work by Professor John F. Berry at the University of Wisconsin - Madison to study the interaction of metal-metal multiply bonded groups with other metal atoms held in close proximity. A new class of coordination compounds will be synthesized that feature heterometallic interactions between a transition metal and an electron-rich metal-metal multiply bonded group. Donation of electron density from the metal-metal multiply bonded group will be probed using multiple physical methods with the aim of discovering new avenues for multi-electron redox reactivity promoted by these compounds. Chemical information will be collected and assembled into pedagogically useful data-based exercises in the form of computer-based hands-on learning modules as supplements to graduate and undergraduate coursework. These data will also be presented to the entirety of the chemical community in the form of an online interactive website or wiki.Heterometallic interactions are important in multi-electron biological processes that are essential to life and are also of industrial importance from the standpoint of energy conversion. The discovery of new oxidative transformations that function via the use of molecular oxygen or hydrogen peroxide is relevant to improving the environmental impact of industrial-scale oxidative chemistry.

无机、生物无机和有机金属化学项目的CAREER奖支持威斯康星大学麦迪逊分校的John F. Berry教授研究金属-金属多重键基与其他金属原子之间的相互作用。将合成一类新的配位化合物，其特征是过渡金属与富电子金属-金属多重键基之间的异金属相互作用。利用多种物理方法探索金属-金属多重键基的电子密度赋能，旨在发现这些化合物促进多电子氧化还原反应的新途径。将收集化学资料，并以计算机为基础的动手学习模块的形式汇编成教学上有用的基于数据的练习，作为研究生和本科生课程的补充。这些数据也将以在线互动网站或维基的形式呈现给整个化学社区。异金属相互作用在生命所必需的多电子生物过程中是重要的，从能量转换的角度来看，也具有工业重要性。通过使用分子氧或过氧化氢来发挥作用的新氧化转化的发现与改善工业规模氧化化学对环境的影响有关。
