Two new unsymmetrical tetrathiafulvalene-based amidoquinline derivatives of 8-amide quinline of PDT-TTF and BTTF (PDT = propylenedithio, TTF = tetrathiafulvalene, BTTF = benzotetrathiafulavalene) (6, 11) have been synthesized and characterized by 1H NMR, MS, and X-ray crystal structural determination. The crystal structures determination shows that they have completely different solid-state constructs due to the different functional group on the side of tetrathiafulvalene group. The molecules of compound 6 are assembled into 1D helical chain along c-axis via hydrogen bond interactions; these helical chains are further connected by the transverse S⋯S van der Waals interactions, thus, resulting to form a layered architecture. The molecules of compound 11 are assembled into 1D chain along c-axis via hydrogen bond and the S⋯S van der Waals interactions. Structures analysis indicate that compound 6 belong to orthorhombic system, space group P2(1)2(1)2(1), with crystal data a = 6.140(7) Å, b = 12.628(14) Å, c = 23.707(3) Å, V = 1838.0(4) Å3, Z = 4, F(000) = 872, R 1 = 0.0570, wR 2 = 0.0910. Compound 11 belong to triclinic system, space group P-1, with crystal data a = 9.532 (2) Å, b = 10.194(2) Å, c = 10.848(3) Å, α = 79.980(5)°, β = 89.342(4)°, γ = 75.226(5)°, V = 1003.1(4) Å3, Z = 2, F(000) = 492, R 1 = 0.0686, wR 2 = 0.1656. The molecules of compound 6 are assembled into 1D helical chain along c-axis via hydrogen bond interactions; these helical chains are further connected by the transverse S⋯S van der Waals interactions, thus, resulting to form a layered architecture.
合成了两种新的不对称四噻富戊二烯基氨基喹啉衍生物 PDT-TTF 和 BTTF 的 8-氨基喹啉(PDT = 丙二硫,TTF = 四噻富戊二烯,BTTF = 苯四噻富戊二烯)(6, 11),并通过 1H NMR、MS 和 X 射线晶体结构测定对其进行了表征。晶体结构测定结果表明,由于四噻富拉伐烯基团一侧的官能团不同,它们的固态结构也完全不同。化合物 6 的分子通过氢键相互作用沿 c 轴组装成一维螺旋链,这些螺旋链通过横向 S⋯S 范德瓦耳斯相互作用进一步连接,从而形成了层状结构。化合物 11 的分子通过氢键和 S⋯S 范德瓦耳斯相互作用沿 c 轴组装成一维链。结构分析表明,化合物 6 属于正方晶系,空间群为 P2(1)2(1)2(1),晶体数据为 a = 6.140(7) Å,b = 12.628(14) Å, c = 23.707(3) Å, V = 1838.0(4) Å3, Z = 4, F(000) = 872, R 1 = 0.0570, wR 2 = 0.0910.化合物 11 属于三菱系,空间群 P-1,晶体数据 a = 9.532 (2) Å, b = 10.194(2) Å, c = 10.848(3) Å, α = 79.980(5)°, β = 89.342(4)°, γ = 75.226(5)°, V = 1003.1(4) Å3, Z = 2, F(000) = 492, R 1 = 0.0686, wR 2 = 0.1656.化合物 6 的分子通过氢键相互作用沿 c 轴组装成一维螺旋链,这些螺旋链通过横向 S⋯S 范德瓦耳斯相互作用进一步连接,从而形成了层状结构。
