原子簇化合物的结构规则

Structural Rules of Cluster Compounds

近年来,国外关于原子簇化合物的研究,诸如合成、性能、结构与结构规律的探讨等极为活跃。我国科学工作者在这方面也做了不少的研究工作。这里仅对结构规则的探讨,作些介绍。其中包括两个方面,一是硼烷和碳硼烷的结构规则,二是金属原子簇化合物的结构规则。一、硼烷和碳硼烷硼烷就是硼氢化合物。五十年代由于高能燃料的研究,合成了许多硼氢化合物,在研究它的性能的同时。

In this paper some new structural rules of cluster compounds have beensuggested as follows: 1.For boron hydrides and carbaboranes the rule is BMO=4n-F=4n-(f-3(s-1)),which is more general than Wade (N+1) rule.The developed rules BMO=4n-(F_1+F_2)-vand BMO=4n-(F_1+F_2)+2 can explain B-B bond joint boron hydride structure andcommon edge joint boron hydride structure respectively. 2.For metal cluster compounds the rule is BMO+NBMO=9N-L. The above rules agree well with the experimental results.
