摘要
介绍了分子或复杂离子的等价式概念,等价式与分子或复杂离子具有相同的价电子数.等价式与分子或复杂离子的结构及它们中的每个原子的成键情况是紧密联系的,同时等价式仅与价电子有关,而与内层电子无关.在等价式中,各种键型之间存在着明确的数学关系式,这个数学关系式完全适用于任何类型的化合物,并且无任何错误之处,同时也扩大了半拓扑图式理论的应用范围.簇合物中存在的键型种类多,成键情况比较复杂.列出了主族原子簇合物和过渡金属簇合物中各种键型之间所符合的数学关系式,这样等价式概念在簇合物中得到了应用,处理结果令人满意.
<Abstrcat>This paper simply introduces the concept about chemical formula of equal valence electrons(CFEVE).The CFEVE has same valence electrons as that of molecules or complicated structural ions.The CFEVE of molecules or complicated structural ions is closely related with structures of chemical bonds of each atom.The CFEVE is also related with valence electrons,but not related with inner electrons.Algebraic equations of kinds of chemical bond types in the CFEVE are definitive.The CFEVE expands applicable range of semitopological graphic theory.The CFEVE is a method that adapts to any kinds of compounds.Clusters have many kinds of chemical bond types,its situation of chemical bonds is very complicated.This paper lists algebraic equations of chemical bond types in main group clusters and transition metal clusters.Thus,the concept of the CFEVE can be applied to clusters,the result is satisfactory.
