as a dual solvate, containing one methanol and one ethanol molecule of crystallization, K+·C13H14Cl2NO9S2−·CH3OH·C2H5OH. The three‐dimensional polymeric network consists of chains containing the potassium ions coordinated and bridged by sugar O atoms, which run parallel to the a axis and are further crosslinked through the sugar molecules. The channels of this network are occupied by the dichlorophenyl
获得用于生物活性的芥子油苷的晶体学分析的晶体已经引起了很多兴趣。获得了(2,3-二氯苯基)芥子油酸钾的双溶剂化物晶体,其中含有一种甲醇和一个乙醇分子,K + ·C 13 H 14 Cl 2 NO 9 S 2 − ·CH 3 OH·C 2 H 5 OH。三维聚合物网络由包含钾离子的链组成,这些钾离子由糖O原子配位和桥连,并平行于a并通过糖分子进一步交联。该网络的通道被二氯苯基取代基以及乙醇和甲醇溶剂分子占据。还确定了S-(2,3,4,6-四-O-乙酰基-β-D-吡喃葡萄糖基)-2,3-二氯苯基乙酰硫羟酸酯,C 21 H 23 Cl 2 NO 10 S的结构,并且确认了硫代氢氧酸酯取代基的β-构型和Z异构体。
