| 摘 要： | 合成了两个由胍盐(G)和4，4’—苯醚二磺酸(PEDS)为主体框架所形成的主— 客体包合物，分别为[(CH6N3)]2[(C12H8O7S2)]·MeOH·2(H20)(1)和[(CH6N3)]2[ (C12H8O7S2)]·(C10H8)(2)．两个化合物都是以P—1空间群结晶，晶胞参数分别为 ：1a＝0．7509(4)nm，b＝1．2113(6)nm，c＝1．5936(8)nm，a＝102．636(10)° ，β＝102．703(11)°,γ＝91．318(10)°；2a＝0．75409(3)nm，b＝1．21584 (5)nm，c＝3．09376(14)nm，a＝81．506(2)°，β＝89．669(2)°，γ＝88． 890(2)°。在这两个晶体结构中，G和PEDS通过氢键形成了双夹层—双柱子的主体 框架，客体分子被包合在平行于a轴方向的晶格空间．这种双夹层—双柱子的主体 框架在由胍盐(G)和有机二磺酸(S)体系所形成的、具有通道结构的主体框架中是较 为少见的．

| Abstract: | Two crystalline inclusion compounds,[(CH_6N_3)]_2[(C_(12)H_8O_7S_2) ]·MeOH·2(H_2O) (1) and [(CH_6N_3)]_2[(C_(12)H_8O_7S_2)]·(C_(10)H_8) (2), were synthesized from guanidinium ions [G, C(NH_2)_3~+] and polar pillar 4,4'-phenyletherdisulfonate (PEDS), and structurally characterized by single crystal X-ray diffraction analysis. Both 1 and 2 crystallize in space group P-1, with cell parameters a = 0.7509(4) nm, b = 1.2113(6) nm, c = 1.5936(8) nm, α = 102.636(10)°, β = 102. 703(11)°, γ = 91.318(10)° (1); and a = 0.75409(3) nm, b = 1.21584(5) nm, c = 3.09376(14) nm, α = 81.506(2)°, β = 89.669(2)°, γ = 88. 890(2)°, respectively. Both the host frameworks of 1 and 2 adopt bilayer-bipillar structures, one of the less common architecture isomer observed in the host G_2S (S = organodisulfonate) framework. |
