Anionic and neutral clusters dominate the cluster chemistry of group 13 and 14 elements, many of which have become classic textbook examples of main group element clusters. However, facilitated by the development of unreactive, weakly coordinating anions, the number of known group 13 and 14 cationic cluster compounds has risen rapidly in recent years. Hence, this review aims to give an overview over this research field, which arouses increasing interest owing to the often unusual structures of the cationic clusters, as well as their application in bond activation chemistry. Challenges of the cluster formation are discussed and suitable starting materials are presented, as well as syntheses, structures and the rich follow-up chemistry of (also mixed) group 13 and 14 cluster cations.
阴离子簇和中性簇在第13族和第14族元素的簇化学中占主导地位，其中许多已成为主族元素簇的经典教科书示例。然而，在惰性、弱配位阴离子发展的推动下，近年来已知的第13族和第14族阳离子簇化合物的数量迅速增加。因此，本综述旨在对这一研究领域进行概述，由于阳离子簇通常具有不寻常的结构及其在键活化化学中的应用，该领域引起了越来越多的关注。讨论了簇形成的挑战，并介绍了合适的起始原料，以及第13族和第14族簇阳离子（包括混合簇阳离子）的合成、结构和丰富的后续化学性质。
