Syntheses and Structures of Two Crystalline Inclusion Compounds G_2PEDS·MeOH·2(H_2O) and G_2PEDS·naphthalene

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 [(CH6 N3) ]2[(C1 2 H8O7S2 ) ]·MeOH·2 (H2 O) (1)和 [(CH6 N3) ]2 [(C1 2 H8O7S2 ) ]·(C1 0 H8) (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 75 0 9(4)nm ,b =1 2 113(6 )nm ,c =1 5 936 (8)nm ,α =10 2 6 36 (10 )°,β =10 2 70 3(11)° ,γ =91 318(10 )°;2a =0 75 4 0 9(3)nm ,b =1 2 15 84 (5 )nm ,c =3 0 9376 (14 )nm ,α =81 5 0 6 (2 )°,β =89 6 6 9(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。

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.
