This project deals with the reduction behavior of substituent-freepolypnictogene ligand complexes (En ligand complexes), which is anarea that has so far been completely disregarded when investigatingthe reactivity of En ligand complexes before this project. As reductionagents, s-block metals, but in particular f-elements, are used, leadingto products with an unprecedented structure via novel reaction typesopening up a new chapter in the organometallic chemistry of thismultifaceted class of substances. In the first phase of this project, inparticular polyphosphorus ligand complexes such as for instance[Cp*Fe(η5-P5)] were employed, and first polyarsenic complexes wereincluded in these investigations leading to novel anionicpolypnictogenide complexes, but particularly to unprecedented 3d-4fmetalpolypnictogenide complexes. In the prolongation of the project,these works will be systematically continued and finalized with aspecial focus on the application of polyarsenic complexes but also ofpolystibane and polybismutane ligand complexes, respectively. Inaddition, the reaction behavior of En ligand complexes towardsnucleophiles (2-electron donators and formal related to 2 electronreductants) of main group elements and d-block-based organometalliccompounds, respectively, is systematically studied, and selectedsubsequent reactions are investigated. Thus, En ligand complexesbecome valuable building blocks in the organometallic chemistry of f-,s-, and d-block elements, respectively.

本项目涉及无取代的多氮族配体络合物（En配体络合物）的还原行为，这是迄今为止在本项目之前阐述En配体络合物的反应性时完全忽略的一个领域。作为还原剂，使用s区金属，特别是f元素，通过新颖的反应类型产生具有前所未有结构的产物，为这类多方面物质的有机金属化学开辟了新的篇章。在该项目的第一阶段，特别是多磷配体配合物，例如[Cp*Fe（η5-P5）]被使用，并且第一多砷配合物被包括在这些研究中，导致新的阴离子多氮族化物配合物，但特别是前所未有的3d-4f金属多氮族化物配合物。在项目的延长期内，这些工作将系统地继续并最终完成，特别侧重于多砷配合物的应用，但也包括多锑烷和多铋烷配体配合物的应用。此外，系统地研究了En配体配合物分别与主族元素亲核试剂（2-电子给体和2-电子还原剂的缩甲醛）和d-嵌段有机金属化合物的反应行为，并选择性地研究了后续反应。因此，En配体络合物分别成为f-，s-和d-区元素的有机金属化学中有价值的构建块。
