Activation of dinitrogen plays an important role in daily anthropogenic life, and the processes by which this fixation occurs have been a longstanding and significant research focus within the community. One of the major fields of dinitrogen activation research is the use of multimetallic compounds to reduce and/or activate N2 into a more useful nitrogen-atom source, such as ammonia. Here we report a comprehensive review of multimetallic-dinitrogen complexes and their utility toward N2 activation, beginning with the d-block metals from Group 4 to Group 11, then extending to Group 13 (which is exclusively populated by B complexes), and finally the rare-earth and actinide species. The review considers all polynuclear metal aggregates containing two or more metal centers in which dinitrogen is coordinated or activated (i.e., partial or complete cleavage of the N2 triple bond in the observed product). Our survey includes complexes in which mononuclear N2 complexes are used as building blocks to generate homo- or heteromultimetallic dinitrogen species, which allow one to evaluate the potential of heterometallic species for dinitrogen activation. We highlight some of the common trends throughout the periodic table, such as the differences between coordination modes as it relates to N2 activation and potential functionalization and the effect of polarizing the bridging N2 ligand by employing different metal ions of differing Lewis acidities. By providing this comprehensive treatment of polynuclear metal dinitrogen species, this Review aims to outline the past and provide potential future directions for continued research in this area.

多核金属配合物活化二氮。



二氮的激活在人类的日常生活中发挥着重要作用,这种固定发生的过程一直是社区内长期且重要的研究焦点。二氮活化研究的主要领域之一是使用多金属化合物来还原和/或活化N 2成为更有用的氮原子源,例如氨。在这里,我们报告了多金属二氮配合物及其对 N 2活化的实用性的全面综述,从第​​ 4 族到第 11 族的d区金属开始,然后扩展到第 13 族(仅由 B 配合物组成),最后稀土和锕系元素。该审查考虑了所有含有两个或多个金属中心的多核金属聚集体,其中二氮被配位或激活(即观察到的产物中N 2三键的部分或完全断裂)。我们的研究包括使用单核 N 2配合物作为构建块来生成同质或异质多金属二氮物质的配合物,这使得人们能够评估异金属物质用于二氮活化的潜力。我们强调了整个元素周期表中的一些共同趋势,例如与 N 2活化和潜在官能化相关的配位模式之间的差异,以及通过使用不同路易斯酸度的不同金属离子来极化桥接 N 2配体的效果。通过对多核金属二氮物质进行综合处理,本综述旨在概述过去并为该领域的继续研究提供潜在的未来方向。
