Metalated three-dimensional icosahedral boron clusters often exhibit high chemical and thermal stability relative to their simple borane counterparts thus making them a convenient object to study the chemistry of metal-boron bonds. The presence of multiple reactive boron vertices makes carboranes unique ligands with unusual steric and electronic requirements. This article summarizes recent developments in coordination chemistry of neutral {C₂B₁₀} carborane clusters with a focus on metal-boron interactions. Several bonding modes are discussed, including neutral borane coordination through bridging B–H··· M interactions, boryl complexes with B -M bonds, multimetallic assemblies, and the BB-carboryne complex containing a three-membered (BB)>Ru metallacycle.

相对于简单的硼烷对应物，金属化的二十面体二十面体硼簇通常表现出较高的化学和热稳定性，因此使其成为研究金属-硼键化学性质的便捷对象。多个反应性硼顶点的存在使碳硼烷具有独特的空间和电子要求，成为独特的配体。本文概述了中性{C ₂ B ₁₀ }碳硼烷簇的配位化学的最新进展，重点是金属-硼的相互作用。讨论了几种键合模式，包括通过桥连B–H···M相互作用的中性硼烷配位，具有B-M键的硼烷基配合物，多金属组装体以及包含三元（BB）> Ru金属环的BB-卡波炔配合物。
