4-吡啶甲醛和S-肼基二硫代甲酸苄酯经醛胺缩合反应合成了一种新型的氨基硫代酸酯衍生物——4-吡啶甲醛氨基硫代酸酯(3),其结构经1H NMR,IR,MS,元素分析及X-射线单晶衍射表征。3属三斜晶系,Pī空间群,晶胞参数a=4.683,b=11.573,c=26.100,α=80.381°,β=88.074°,γ=89.40°,V=1 393.83,Z=4。运用UV-Vis并结合理论计算,初步研究了3的光学性能。3的λmax位于336 nm和403 nm。

4-Pyridinecarboxaldehyde and S-hydrazinyl dithiocarboxylate were synthesized by the aldehyde amine condensation reaction, a novel amino thioester derivative, 4-pyridinecarboxaldehyde amino thioester (3), whose structure Characterization by 1H NMR, IR, MS, elemental analysis and X-ray single crystal diffraction. 3 belong to the triclinic system, Pī space group, the unit cell parameters a = 4.683, b = 11.573, c = 26.100, α = 80.381 °, β = 88.074 °, γ = 89.40 °, V = 1 393.83 , Z = 4. Using UV-Vis combined with theoretical calculations, preliminary study of the optical properties of 3. The λmax of 3 lies at 336 nm and 403 nm.
