In this Concept we discuss how the chemistry of coinage metal complexes based on alkynyl ligands has developed over the past decades. The rich coordination of alkynyl, that exhibit both η (end-on) and η (side on) modes, includes non-bridged systems, as well as bridging of up to four (or six) metal centres. Resulting metal clusters often exhibit highly regular structures and typical coordination motifs forming fascinating assemblies exploiting this versatile coordination. Metallophilic interactions are often an important driving force for the formation of large clusters. In addition, the use of co-ligands as well the possibility to encapsulate counter ions greatly increases the chemical and structural diversity. Herein we attempt to summarize and highlight design principles towards multinuclear homo and hetero-bi-metallic coinage metal clusters of alkynyl ligands.
在本综述中，我们讨论了过去几十年中基于炔基配体的金属配合物化学的发展。炔基的配位化学非常丰富，既可以呈现端基（η）模式，也可以呈现边桥（η）模式，包括非桥联体系，以及多达四个（或六个）金属中心的桥联。由此形成的金属簇通常具有高度规则的结构和典型的配位模式，通过这种多功能的配位方式形成了引人入胜的组装体。金属键相互作用通常是形成大簇的重要驱动力。此外，使用辅助配体以及封装抗衡离子的可能性极大地增加了化学和结构的多样性。本文中，我们尝试总结和强调设计具有炔基配体的多核同/异金属金属配合物的原则。
