n this article, the basic physical and chemical properties, preparation, and applications of germanium and its related compounds are all described in detail. The whole chapter is divided into 12 sections, namely, introduction, analysis, the element, hydrides, boron derivatives, nitrogen compounds, phosphorus and arsenic compounds, oxygen-bonded compounds, sulfides, selenides and tellurides, halides, metalloid- and metal-bonded compounds, and polyoxometalates of germanium. In each section, some new development in the synthesis and applications of new compounds are included following the fundamental information.
In the introduction section, the discovery, distribution, effect on organisms, basic chemistry, and application of germanium are given briefly.
The analysis section gives a concise description of the main analysis processes.
The preparation, basic physical and chemical properties of metal germanium, and anionic germanium clusters are included in the element section.
In the following sections, different germanium compounds are described mainly according to the different valence germanium exhibits. Their fundamental synthetic routes, discovery and synthesis of new compounds, and the new development in the related fields are emphasized. In particular, contents concerning the construction of framework materials, the synthesis of polyoxometalates, which represent the tendency of development in inorganic chemistry, are presented comprehensively.
More than seventy equations are used to illustrate certain reactions, and detailed information of some important compounds and their synthetic routes are also given in the form of structures, schemes, and figures. Certain data, properties and structure information of germanium, and its compounds are listed in some tables.
