In this project, funded by the Chemical Synthesis program of the Chemistry Division, Professor John F. Berry of the University of Wisconsin - Madison is studying metal compounds that feature a linear chain of three metal atoms supported by nitrogen- or oxygen-donor groups (ligands). Compounds with chains of metal atoms find applications in in biological and synthetic catalysis, materials chemistry, energy conversion, molecular magnetism, and single-molecule conductance. The project develops the preparation of compounds that have never before been prepared and thus their reactivity is unknown. The three atom units can be envisaged to possess important magnetic and electrical properties. Professor Berry is strongly committed to communicating science to the general public through several major outlets. Professor Berry is a Fellow of the Wisconsin Initiative for Science Literacy (WISL) and has been involved in many WISL events. He and his group participate in "Concert at Chemistry" presenting musical compositions to the general public, and commenting on the strong connections between science and the arts. Professor Berry has also participated in "Conversations in Chemistry", a televised public lecture for an audience of K?12 science teachers in which the topic was the connections between chemistry, music composition and the arts. The Berry lab is also involved in outreach programs at the graduate, college, and high school levels that engage underrepresented minority students. At the graduate and college level, Berry is an active participant in the Chemistry Opportunities (CHOPS) program. CHOPS brings 20 highly qualified undergraduates to campus in which they are exposed to the graduate school experience by being paired up with graduate student hosts. These students typically come from underrepresented backgrounds. The project involves planned, hypothesis-driven, systematic synthetic, physical, and spectroscopic studies that give insights into important structure/property relationships in heterotrimetallic compounds that contain a metal-metal multiply bonded unit and a third metal from the f-, late d-, or main group elements. In particular, the project focuses on: (1) redox chemistry, (2) magnetic behavior, and (3) electron transport properties. The methodologies include organic synthesis, high-temperature synthetic techniques, manipulation of air sensitive compounds, spectroscopic and electrochemical characterization methods, and the use of density function theory to model electronic structure. This project offers excellent training for the graduate students and undergraduates who work on this project. This training and learning is intimately integrated with discovery of novel compounds and exploration of their properties. This project provides excellent training for the graduate students and undergraduates who learning a multitude of synthetic, characterization, and computational techniques.

在该项目中，由化学系化学合成项目资助，威斯康星大学麦迪逊分校的 John F. Berry 教授正在研究具有由氮或氧供体基团（配体）支撑的三个金属原子线性链的金属化合物。具有金属原子链的化合物在生物和合成催化、材料化学、能量转换、分子磁性和单分子电导方面有应用。该项目开发了以前从未制备过的化合物的制备方法，因此它们的反应性未知。可以设想这三个原子单元具有重要的磁和电特性。贝里教授坚定地致力于通过几个主要渠道向公众传播科学。 Berry 教授是威斯康星州科学素养倡议 (WISL) 的成员，并参与了许多 WISL 活动。 他和他的团队参加“化学音乐会”，向公众展示音乐作品，并评论科学与艺术之间的紧密联系。贝里教授还参加了“化学对话”，这是一场针对 K-12 科学教师观众的电视公开讲座，主题是化学、音乐创作和艺术之间的联系。贝瑞实验室还参与了研究生、大学和高中层面的外展项目，吸引少数族裔学生参与。在研究生和大学阶段，Berry 积极参与化学机会 (CHOPS) 计划。 CHOPS 将 20 名高素质本科生带到校园，与研究生接待员配对，让他们体验研究生院的体验。这些学生通常来自代表性不足的背景。该项目涉及有计划的、假设驱动的、系统的合成、物理和光谱研究，深入了解异三金属化合物的重要结构/性质关系，这些化合物含有金属-金属多重键合单元和来自 f-、晚 d- 或主族元素的第三种金属。该项目特别关注：（1）氧化还原化学，（2）磁性行为，以及（3）电子传输特性。这些方法包括有机合成、高温合成技术、空气敏感化合物的操纵、光谱和电化学表征方法以及使用密度函数理论来模拟电子结构。该项目为从事该项目的研究生和本科生提供了良好的培训。这种培训和学习与新化合物的发现及其特性的探索紧密结合。该项目为学习多种合成、表征和计算技术的研究生和本科生提供了良好的培训。
