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.

这项职业生物，生物无机和有机金属化学计划支持威斯康星大学 - 麦迪逊大学约翰·贝里教授的工作，研究了金属金属多键键群体与其他金属原子与近距离接近的其他金属原子的相互作用。将合成一类新的协调化合物，该化合物具有过渡金属与富含电子金属倍数键组之间的异质相互作用。将使用多种物理方法探测从金属金属多键组中捐赠电子密度，以发现这些化合物促进的多电子氧化还原反应性的新途径。化学信息将以基于计算机的动手学习模块的形式收集并组装成教学上有用的基于数据的练习，作为研究生和本科课程的补充。这些数据还将以在线互动网站或Wiki的形式呈现给整个化学界。在多电子生物学过程中，对于生命至关重要的多电子生物学过程很重要，并且从能量转化的角度也具有工业意义。通过使用分子氧或过氧化氢来发现新的氧化转化与改善工业规模氧化化学的环境影响有关。
