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、具有通道结构的主体框架中是较为少见的
Two host-guest inclusion complexes formed by the main framework of guanidinium salt (G) and 4,4’-phenylene disulfonic acid (PEDS) were synthesized, which were [(CH6N3)] 2 [(C1 2 H8O7S2 ) • MeOH • 2 (H2 O) (1) and [(CH6 N3)] 2 [(C1 2 H8 O7S2)] • (C1 0 H8) (2) Both compounds are crystallized in a P 1 space group, The unit cell parameters are as follows: 1a = 0 75 0 9 (4) nm, b = 1 2 113 6 nm, c = 1 5936 8 nm, α = 10 26 36 10, 10 2 70 3 (11) °, γ = 91 318 (10) °; 2a = 0 75 4 0 9 (3) nm, b = 1 2 15 84 α = 81 5 0 6 (2) °, β = 89 6 6 9 (2) °, γ = 88 890 (2) °. In both crystal structures, G and PEDS form a double sandwich by hydrogen bonding - the main framework of the double-column, the guest molecules are enclosed in the lattice space parallel to the a-axis.The main framework of this double-sandwich-double-column is in the framework of guanidine salt (G) and organodisulfonic acid The formed body frame with the channel structure is less common
