| 中文摘要: |
| 通过吡啶盐与3，4-二甲氧基苯甲醛在甲醇中反应，得到了一种新型的化合物，即4-[（3"，4"-二甲氧基)苯乙烯基]-N-甲基吡啶高氯酸盐，分子式为C16H18ClNO6。化合物的结构通过红外、元素分析、氢谱、电喷雾质谱和X-单晶衍射仪进行分析与表征。结果表明：该化合物属正交晶系，空间群Pbca，晶胞参数a = 13.5897(11) nm, b = 13.9126(11) nm, c = 17.3485(14) nm, α = 90 °, β = 90 °, γ = 90 °, Mr = 355.76, V = 3280.0(5) nm3, Z = 8, F(000) = 1488, Dc = 1.181 g/cm3, μ = 0.265 mm?1。而且还研究了该化合物的光学性质。 |
| 英文摘要: |
| A novel compound of 4-[2-(3,4-dimethoxyphenyl)ethenyl]-N-methylpyridinium perchlorate, C16H18ClNO6, was synthesized by the reaction of pyridinium salt with 3,4-dimethoxybenzaldehyde in methanol. The structure of the compound was determined by IR, elemental analysis, 1H NMR and ESI-MS. And the crystal of the compound was further determined by X-ray single crystal diffraction. The crystal belongs to orthorhombic system with space group Pbca, a = 13.5897(11) nm, b = 13.9126(11) nm, c = 17.3485(14) nm, α = 90 °, β = 90 °, γ = 90 °, Mr = 355.76, V = 3280.0(5) nm3, Z = 8, F(000) = 1488, Dc = 1.181 g/cm3, μ = 0.265 mm?1. And the optical property of the title compound was further studied. |
