Sulfur - metal compound having a variety of structures , is studied in recent years , a growing number of inorganic multifunctional materials . The synthesis of this class of compounds , and is becoming a inorganic chemical research hotspot . Solvothermal (hydrothermal ) synthesis method is an easy to generate a new phase , the guide to the new structure of the effective methods of inorganic synthesis . With this method , you can get a lot of new, special structure of metal chalcogenides . This paper , the development of a synthetic multi- metal sulfur arsenic compounds solvothermal synthetic route . Use this route to synthesize novel compounds [ NH 3 < / sub > the CH 2 CH 2 NH 3 < / sub > ] AgAsS < sub> 4 . The synthesis reaction route is simple and easy to operate, and the product obtained is pure , good crystal quality . Synthesized compounds CH the [ NH 3 2 CH 2 NH 3 < / sub > ] AgAsS 4 3 , Dc = 2.558g/cm 3 , μ = 6.256mm < sup> -1 , F (000) = 1440, R = 0.0340, wR = 0.0859. The compound has an interesting one-dimensional infinite chain structure , the structure of the unit by the [ AgAsS 4 < / sub >] 2 - and protonated ethylenediamine constitute . SEM, IR, DSC-TGA Characterization of the compounds also . Explore the influencing factors of synthetic routes , found that the solvent affects the synthesis reaction . The most suitable for the above compound from ethanol / water volume ratio of 5/ 1 to 8/1, when ethanol / water volume ratio of 4/ 1 , the synthesis of another new silver sulfur arsenic compound . The synthetic route has general applicability and can also be used to synthesize other metal sulfur arsenic compound .
