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，由化学司的化学合成计划资助，威斯康星大学的约翰·贝里教授 - 麦迪逊研究金属化合物，这些化合物具有由三个金属原子的线性链，由三个金属原子组成，并由氮或氧气含量组（配体）（配体）支撑。具有金属原子链的化合物在生物学和合成催化，材料化学，能量转化，分子磁性和单分子电导中发现了应用。该项目开发了从未准备过的化合物的制备，因此其反应性是未知的。可以设想三个原子单元具有重要的磁性和电性能。贝里教授强烈致力于通过几个主要渠道向公众传达科学。贝里教授是威斯康星州科学素养倡议（WISL）的会员，并参与了许多WISL活动。 他和他的小组参加了“化学音乐会”，向公众展示了音乐作品，并评论了科学与艺术之间的牢固联系。贝里教授还参加了“化学对话”，这是一项电视上的公开演讲，供K？12科学老师的观众进行，其中这个话题是化学，音乐作品与艺术之间的联系。 Berry Lab还参与了研究生，大学和高中级别的外展计划，这些计划与代表性不足的少数民族学生有关。在研究生和大学一级，Berry是化学机会（Chops）计划的积极参与者。 Chops将20位高素质的本科生带到了校园，通过与研究生院的主持人配对，他们接触了研究生院的经验。这些学生通常来自代表性不足的背景。该项目涉及计划的，假设驱动的，系统的合成，物理和光谱研究，这些研究可深入了解杂质金属化合物的重要结构/性质关系，这些结构/性质关系包含来自F-，晚D或主组元素的金属金属多粘结单元和第三个金属。特别是，该项目的重点是：（1）氧化还原化学，（2）磁性行为和（3）电子传输特性。该方法包括有机合成，高温合成技术，对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建模电子结构。该项目为从事该项目的研究生和本科生提供了出色的培训。这种培训和学习与发现新颖的化合物和对其性质的探索密切相结合。该项目为研究生和本科生提供了出色的培训，他们学习了许多合成，表征和计算技术。
