本文从硼烷原子簇化合物(Bn Hm)~(q-)的结构特点出发,定义了结构特征值为μ=m+q-n。易知,其成键价电子数为4n+μ。根据μ值,可以直接从硼烷的分子式来预测它的可能结构。可以把硼烷分成单纯型和双联型。前者指单个封闭型,巢型或网型结构的硼烷,后者指单纯型硼烷的各种可能组合,即包括封—封,巢—巢,网—网,封—巢,封—网,巢—网的各种连结方式。硼烷的结构可按结构特征值μ来分类。对于一种类型的硼烷,有一个相应于这种结构特征的μ值。对于单纯型硼
Based on the structural features of Bn Hm ~ (q-), the structural characteristic value is defined as μ = m + q-n. Easy to know, the bond price of electronic number 4n + μ. Based on the μ value, it is possible to predict its possible structure directly from the molecular formula of borane. Borane can be divided into simplex and double type. The former refers to a single closed, nested or net structure of borane, the latter refers to the simple type borane various possible combinations, including seal - seal, nests - nests, nets - nets, nests, nets - , Nest - a variety of links to the network. The structure of borane can be classified according to the structural characteristic value μ. For one type of borane, there is a value of μ that corresponds to this structural feature. For simple type boron
