摘要
键角是决定物质分子空间结构的一个重要因素,与键长一起决定着物质分子的极性和对称性,从而影响物质的物理和化学性质。本文对影响无机共价分子中键角的因素进行了较系统地分析和总结,掌握这些影响因素可实现对分子键角大小的准确判断,更好地运用无机结构相关理论知识。
As an important factor to determine the molecular geometries, bond angle, together with bond length, control the polarity and symmetry of molecule. As a result, the physical and chemical properties of compounds were affected. In this paper, the factors affecting the bond angle of inorganic covalent molecules were analyzed and summarized systematically. The mastery of these factors will facilitate to acquire the correct judgment about the bond angle and apply the theory about inorganic structure better.
