本文在一般性地讨论多面体硼烷和碳烷骨架几何性质的基础上,探讨了以已知封闭型硼烷(碳烷)骨架为基础,在保持对称性下依次进行截角-戴帽,交替地得到多面体碳烷(硼烷)-硼烷(碳烷)骨架系列的方法,并以构造I_h和O_h对称性系列作为例子。在此基础上,讨论了可能存在的多面体硼烷和碳烷以及高硼和高碳裸体原子簇的结构和性质。 Based on the general discussion of the geometrical properties of polyhedral boranes and alkane skeletons, this paper discusses the geometric properties of polyhedral boranes and alkane skeletons. Based on the known closed borane skeletons, (Polyborane) - borane (alkane) skeleton series of methods, and to construct I_h and O_h symmetry series as an example. On this basis, the possible structures and properties of polyhedral boranes and alkanes as well as clusters of high-boron and high-carbon nude clusters are discussed.
