|Section2= |Section3= |Section7= }} Tin(IV) sulfide is a compound with the formula SnS2. The compound crystallizes in the cadmium iodide motif, with the Sn(IV) situated in "octahedral holes' defined by six sulfide centers.〔Wells, A.F. (1984) Structural Inorganic Chemistry, Oxford: Clarendon Press. ISBN 0-19-855370-6.〕 It occurs naturally as the rare mineral berndtite.〔Vaughan, D. J.; Craig, J. R. "Mineral Chemistry of Metal Sulfides" Cambridge University Press, Cambridge: 1978. ISBN 0-521-21489-0.〕 It is useful as semiconductor material with band gap 2.2 eV. ==Reactions== The compound precipitates as a brown solid upon the addition of H2S to solutions of tin(IV) species. This reaction is reversed at low pH. Crystalline SnS2 has a bronze colour and is used in decorative coating〔Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5.〕 where it is known as mosaic gold. The material also reacts with sulfide salts to give a series of thiostannates with the formula ()m()n2n :SnS2 + S2− → 1/xx. 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「Tin(IV) sulfide」の詳細全文を読む スポンサード リンク
