混合价化合物是一类重要的化合物,它包括小分子和大分子无机化合物、无机材料和金属有机化合物,而无机化合物和无机材料更为普遍。研究和了解混合价化合物的结构和性质以及结构和性质的关系,在理论上和实际应用上都具有重要意义,而且可以丰富无机化学的教学内容。本文将就混合价化合物及其分类、桥基配体的作用、以及电荷定域两态结构模型进行讨论。 Mixed valence compounds are a class of important compounds that include small molecules and macromolecular inorganic compounds, inorganic materials, and organometallic compounds, while inorganic compounds and inorganic materials are more prevalent. To study and understand the structure and properties of mixed valence compounds and the relationship between their structure and properties is of great significance both theoretically and practically, and can enrich the teaching content of inorganic chemistry. This article will discuss the mixed valence compounds and their classification, the role of bridge ligands, and the charge domain two-state model.
