Like the silicon dioxide, this material is polymeric, but it adopts a 1-dimensional structure quite different from the usual forms of SiO2. ==Synthesis, structure, and properties== The material is formed by heating silicon and sulfur or by the exchange reaction between SiO2 and Al2S3. The material consists of chains of edge-shared tetrahedra, Si(μ-S)2Si(μS)2, etc.〔 A printing error in this book states that rSiSi is 214 picometers, when in fact that distance describes rSiS.〕 Like other silicon sulfur-compounds (e.g., bis(trimethylsilyl)sulfide) SiS2 hydrolyzes readily to release H2S. In liquid ammonia it is reported to form the imide Si(NH)2 and NH4SH, but a recent report has identified crystalline (NH4)2()·2NH3 as a product which contains the tetrahedral thiosilicate anion, SiS3(NH3). Reaction with ethanol gives the alkoxide, tetraethyl orthosilicate and H2S.〔 Reaction with sodium sulfide, magnesium sulfide and aluminum sulfide give thiosilicates.〔 SiS2 is claimed to occur in certain interstellar objects. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Silicon sulfide」の詳細全文を読む スポンサード リンク
