The dark-red crystalline compound is soluble in boiling water, acetone, and ethanol.〔T. Peppel, C. Schmidt and M. Köckerling, "Synthesis, Properties, and Structures of Salts with the Reineckate Anion, ()−, and Large Organic Cations", ''Zeitschrift für anorganische und allgemeine Chemie'' 2011, 637, 1314–1321. 〕 The chromium atom is surrounded by six nitrogen atoms in an octahedral geometry. The NH3 ligands are mutually trans and the CrNCS groups are linear. The salt crystallizes with one molecule of water.〔 ==Structure== It was first reported in 1863.〔Reinecke, A. "Über Rhodanchromammonium-Verbindungen" ''Annalen der Chemie und Pharmacie'', volume 126, pp. 113–118 (1863). .〕 NH4() is prepared by treatment of molten NH4SCN (melting point around 145–150 °C) with (NH4)2Cr2O7. 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「Reinecke's salt」の詳細全文を読む スポンサード リンク
