本文系统地考察了晶体的组成(组分数β=2,β=3,β≥4)与配位数之间的关系.提出了配位平衡方程和电子平衡方程。分析了A_xB_y、A_xB_yC_z和A_xB_yC_zD_w等型式的晶体,给出了晶体的组成与配位数相互联系的规律。将此规律应用于离子晶体,推算出原子的配位数和它们在周期表族的编号之间的关系。在配位平衡方程与电子平衡方程的基础上,导出了Pauling由经验得到的静电键规则—Pauling第二规则。
In this paper, we systematically investigated the relationship between the crystal composition (compositional number β = 2, β = 3, β≥4) and coordination number, and proposed the coordination equilibrium equation and the electron balance equation. The types of crystals such as A_xB_y, A_xB_yC_z and A_xB_yC_zD_w were analyzed, and the regularity of the relationship between the crystal composition and coordination number was given. Applying this law to ionic crystals, the relationship between the coordination numbers of atoms and their numbers in the periodic table is deduced. Based on the coordination equilibrium equation and the electron balance equation, Pauling’s rule of the electrostatic bond derived from experience-Paul’s second rule is derived.
