Following the former synthetic work on group 6 metal complexes, aminocarbyne (aminoalkylidyne) ligands have become popular across various transition metal groups. They are versatile ligands adapting to variable coordination modes (i.e. terminal, bridging and multibridging), metal oxidation states and co-ligands. They possess peculiar structural and reactivity features compared to nitrogen-lacking alkylidyne ligands and, especially when bridging coordinated to diiron bis-cyclopentadienyl frames, exhibit a rich chemistry enabling the construction of unusual organometallic species. The bonding, electronic and steric effects, structural and spectroscopic features and reactivity trends of aminocarbyne ligands are reviewed with reference to the distinct cases (nuclearity of the complex and coordination mode, nature of the metal element, and type of substituent(s) on the aminocarbyne).

继之前对第 6 族金属配合物的合成工作之后，氨基碳炔（氨基烷基炔）配体在各种过渡金属族中变得流行。它们是适应可变配位模式（即末端、桥连和多桥连）、金属氧化态和共配体的通用配体。与缺氮亚烷基配体相比，它们具有独特的结构和反应性特征，尤其是在与二铁双环戊二烯基框架配位的桥接时，表现出丰富的化学性质，能够构建不寻常的有机金属物种。结合不同情况（络合物的核性和配位模式，金属元素的性质，
