钠和铵物质所采用的总体结构非常相似，由杯芳烃的双层与由铵离子和水分子组成的层交替组成。阳离子和水分子通过氢键负责层间和层内的连接。[8]然而，极性层的组成从钠盐中的四个钠离子和十一个水分子变为铵盐中的五个铵离子、一个水分子和一个甲基硫酸根阴离子。9· 10** 硫酸甲酯的取向使得
The gross structures adopted by the sodium and ammonium species are quite similar, consisting of bilayers of calixarenes alternating with layers composed of ammonium ions and water molecules. The cations and water molecules are responsible for both the inter-and intra-linking of the layers via hydrogen bonds. 8 The composition of the polar layer, however, changes from four sodium ions and eleven water molecules in the sodium salt to five ammonium ions, one water molecule, and a methyl sulfate anion in the ammonium salt. 9· 10** The methyl sulfate is oriented such
