合成了环糊精与对苯二酚包合物[(C_(42)H_(70)O_(35)·(C_6O_2H_(6))_3·(H_2O)_(21.2)·(CH_3OH)_2],并用X射线单晶衍射法测定了晶体结构.该晶体属三斜晶系,空间群为 P1,晶胞参数:a= 1.550 0(1) um,b= 1.553 6(1) um, c= 1.824 6(1) um, a= 113.17(2)°,γ= 99.12(2)°, γ= 103.37(3)°, V= 3.773 9(4)um~3, Z= 1; Dc= 1.343 g/cm~3, μ= 0.124 mm~(-1), F(000)= 1594, R= 0.079 5, S= 0.963 9.晶体结构测定表明,客体分子在主体分子空腔内的位置以及主-客体包合物稳定存在的一个重要因素是客体分子的极性基团的溶剂化程度.
The synthesis of cyclodextrin complex with hydroquinone [(C_ (42) H_ (70) O_ (35) · (C_6O_2H_ (6)) _3 · (H_2O) _ (21.2) · (CH_3OH) _2 ], And the crystal structure was determined by single crystal X-ray diffraction. The crystal belongs to triclinic system with space group P1 and unit cell parameters: a = 1.550 0 (1) um, b = 1.553 6 (1 ) Um, c = 1.824 6 (1) um, a = 113.17 (2) °, γ = 99.12 (2) °, γ = 103.37 (3) °, V = 3.773 9 D = 1.343 g / cm ~ 3, μ = 0.124 mm -1, F (000) = 1594, R = 0.079 5, S = 0.963 9. The crystal structure determination shows that the position of the guest molecule in the host molecule cavity and the stable existence of the host-guest inclusion complex exist as the solvent of the polar group of the guest molecule Degree.
