The crystal structures of di-ethylaminogossypol with ethyl acetate (DEAG-EA) and pyridine (DEAG-P) were studied by room-temperature X-ray diffraction. The host-to-guest molecule ratio in these complexes is 2:1 for DEAG-EA and 2:5 for DEAG-P. The crystal and cell parameters for DEAG-EA are C34H40N2O6·0.5(C4H8O2), M = 660.78, triclinic, space group P-1, a = 11.316(2) Å, b = 12.082(2) Å, c = 15.085(3) Å, α = 73.34(3)°, β = 73.32(3)°, γ = 73.61(3)°, V = 1,847.3(7) Å3, Z = 2, and d calc. = 1.188 g/cm3 and for DEAG-P are C34H40N2O6·2.5(C5H5 N), M = 769.91, triclinic, space group P-1, a = 9.6090(19) Å, b = 14.894(3) Å, c = 16.038(3) Å, α = 90.66(3)°, β = 106.25(3)°, γ = 103.17(3)°, V = 2138.7(9) Å3, Z = 2, and d calc. = 1.195 g/cm3. In both structures, the di-ethylaminogossypol molecules are in the enamine form, which is the same tautomer found for other reported Schiff base gossypol derivatives. The enantiomeric gossypol molecules of each structure form different centrosymmetric dimer assemblies. These assemblies pack differently in each solvate. Crystal structures of the solvates of di-ethylaminogossypol with ethyl acetate and pyridine were determined by X-ray diffraction.
室温 X 射线衍射研究了二乙胺基苔藓酚与乙酸乙酯(DEAG-EA)和吡啶(DEAG-P)的晶体结构。在这些复合物中,DEAG-EA 的主客分子比为 2:1,DEAG-P 的主客分子比为 2:5。DEAG-EA 的晶体和晶胞参数为 C34H40N2O6-0.5(C4H8O2),M = 660.78,三菱形,空间群 P-1,a = 11.316(2) 埃,b = 12.082(2) 埃,c = 15.085(3) Å, α = 73.34(3)°, β = 73.32(3)°, γ = 73.61(3)°, V = 1,847.3(7) Å3, Z = 2, and d calc. = 1.188 g/cm3,DEAG-P 为 C34H40N2O6-2.5(C5H5 N),M = 769.91,三菱形,空间群 P-1,a = 9.6090(19) 埃,b = 14.894(3) 埃,c = 16.038(3) 埃,α = 90.66(3)°,β = 106.25(3)°,γ = 103.17(3)°,V = 2138.7(9) 埃3,Z = 2,d calc. = 1.195 g/cm3。在这两种结构中,二乙氨基戈西泊醇分子都是烯胺形式,这与其他已报道的席夫碱戈西泊醇衍生物的同系物相同。每种结构的对映体棉酚分子都形成了不同的中心对称二聚体组合。这些组合体在每种溶解物中的堆积方式都不同。通过 X 射线衍射测定了二乙基氨基戈西泊酚与乙酸乙酯和吡啶的溶解物的晶体结构。
