Thermolysis of an in situ generated intermediate, obtained from the reaction of [Cp*MCl₂]₂ (M = Rh, Ir) and LiBH₄·thf, with Se powder and [Zn(BH₄)₂] afforded the two unusual heterotrimetallic complexes [(Cp*MB₂H₃Se₂)₂(μ₄-Zn)] (1, M = Ir; 2, M = Rh), along with [(Cp*M)₂B₂H₂Se₂] (M = Rh, Ir; Cp* = η⁵-C₅Me₅). Clusters 1 and 2 are distinct due to the presence of a tetracoordinated Zn(II) in the Se₄ pocket molded by the Se atoms of two {Cp*MB₂H₃Se₂} units. These clusters belong to a rare class of metal-centered commo-bis(metallaheteroborane) species. The molecular structures of 1 and 2 can be viewed as two arachno-metallaheteroborane subclusters conjoined at the common zinc atom that obey Mingos’ fusion formalism. Both 1 and 2 have been comprehensively characterized by multinuclear NMR, IR, and UV–vis spectroscopy, mass spectrometry, and single-crystal X-ray diffraction techniques. All experimental results are well supported by theoretical studies.

金属中心commo双（metallaselenaborane）：Heterotrimetallic系统轴承一个锌（II）中心

的热分解就地生成的中间，从混合[Cp *的MC1的反应得到₂ ] ₂（M =铑，铱）和的LiBH ₄ ·THF，用硒粉并且，[Zn（BH ₄）₂ ]，得到两种不同寻常heterotrimetallic配合物[（CP * MB ₂ ħ ₃硒₂）₂（μ ₄ -Zn）]（1，M =铱; 2，M = RH），以及[（CP * M）₂乙₂ ħ ₂硒₂ ] （M =铑，铱;的Cp * =η ⁵ -C ₅我₅）。集群由于在由两个{Cp * MB ₂ H ₃ Se ₂ }单元的Se原子模制的Se ₄口袋中存在四配位的Zn（II），所以图1和图2是不同的。这些簇属于一种罕见的类的金属中心commo双（metallaheteroborane）物种。1和2的分子结构可以看作是两个服从Mingos聚变形式的锌原子相连的Arachno- metallaheteroborane亚簇。既1和2已通过多核NMR，IR和UV-vis光谱，质谱和单晶X射线衍射技术对其进行了全面表征。所有实验结果均得到理论研究的充分支持。
