原于簇化合物的化学是当前活跃的研究领域之一。Lipscomb、wade、唐敖庆等对它们的结构做了许多工作。关于硼烷和碳硼烷的成键轨道总数——BMO,Wade提出了2n+1等规则,并把它推广到金属原子簇化合物;唐敖庆对硼烷和金属原子簇化合物,分别提出了4n—F和9n—l的拓扑规则。Wade从顶点数出发,唐敖庆则考虑面数和边数,我们根据多面体的拓扑性质,讨论二者间的关系。 Chemistry of the original cluster compounds is one of the most active areas of research. Lipscomb, wade, Tang Aoqing and so on their structure has done a lot of work. With regard to the total number of bonding orbital of borane and carborane - BMO, Wade proposed 2n + 1 and other rules and extended it to metal cluster compounds; Tang Aoqing borane and metal cluster compounds were proposed 4n- F and 9n-l topology rules. Wade starts from the vertices, while Tang Aoqing considers the number of faces and the number of sides, and we discuss the relationship between the two according to the topological nature of the polyhedron.
