元素通常有一定的原子价,如氢是一价,氧是二价,银是一价,铜是二价等。但是在早期的化学中,就发现不符合原子价规律的化合物,开始叫“复杂化合物”,后来叫配位化合物,现在又叫络合物。络合物的种类很多,应用也广,简要地叙述于下。一、络合物的概念1.维尔纳的配位理论关于配位化合物的结构,曾引起化学家的争论。1893年维尔纳(A.Werner)提出了配位理论,是配位化学的奠基人。它根据大量实验结果,认为简单的原子价概念不能说明配位化合
Elements usually have a certain atomic value, such as hydrogen is a monovalent, oxygen is bivalent, silver is monovalent, copper is bivalent and so on. However, in earlier chemistry, it was found that compounds that did not conform to the law of atomic value began to be called “complex compounds” and later called coordination compounds, now called complexes. Many types of complexes, the application is also wide, briefly described in the next. First, the concept of complex 1. Werner coordination theory The coordination compound structure, has aroused controversy chemists. In 1893 A. Werner proposed coordination theory, is the founder of coordination chemistry. It based on a large number of experimental results, that the concept of simple atomic valence can not explain the coordination complex
