The silver reacts with the sulfur produced by the thermal decomposition of the S4N4 to form Ag2S, and the resulting Ag2S catalyzes the conversion of the S4N4 into the four-membered ring S2N2, :S4N4 + 8 Ag → 4 Ag2S + 2 N2 :S4N4 → 2S2N2 An alternative uses the less explosive S4N3Cl. S2N2 decomposes explosively above 30°, and is shock sensitive.〔 It readily sublimes, and is soluble in diethyl ether. Traces of water cause it to polymerize into S4N4.〔 In the solid state it spontaneously polymerizes forming (SN)x.〔 It forms adducts with Lewis acids via a nitrogen atom, e.g. S2N2 · BCl3, S2N2 · 2AlCl3, S2N2 · SbCl5, S2N2 · 2SbCl5.〔 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「Disulfur dinitride」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
