Progress in the Synthesis of Germanium Chalcogenides Containing Silver

: In recent years, germanium containing sulfur compounds have attracted much attention due to their complex structural properties and potential applications, and have been widely used in nonlinear optics, molecular sieve, ion exchange and so on. Group 11 elements Ag have been proved to be successful multifunctional elements often used for synthesis, because they have rich coordination modes and electrothermal properties. In addition, they also enhance the metalophilic interaction, overcome the repulsive force between cationic metal centers, and more easily enter the skeleton to form new materials with unique topological structures. The potential applications of these materials extend beyond traditional fields. The synthesis and structure of germanium chalcogenides containing transition metal silver are reviewed in this paper. Various coordination modes of structural units in the basic framework of transition metal silver and germanium sulfide compounds, synthesis methods, structural characteristics and applications of different germanium sulfide compounds containing transition metal silver are summarized. And the synthesis of germanium sulfide compounds containing silver when alkali metals, transition metal complexes, organic amines are used as structure guide agent.
