摘要 A novel pyridine-contained a-cyanostilbenzene Schiff base, （Z）-3-（4-butoxy- phenyl）-2-（4-（（E）-pyridin-2-yl-methyleneamino）phenyl）acrylonitrile （L）, has been synthesized and characterized by 1H NMR, 13C NMR, FT-IR spectra and single-crystal X-ray diffraction. Single-crystal data show that compound L belongs to the triclinic system, space group P1, with a = 8.759（4）, b = 10.779（4）, c = 12.594（5） A, a= 65.873（4）, β = 88.332（5）, 7= 73.800（5）°, M,. = 381.46, V= 1037.2（7） A3, Z = 2, Dc = 1.221 g/cm-3,μ = 0.076 mm-1, F（000） = 404, gint = 0.0311, R （I〉 20（I）） = 0.0484, wR （I 〉 20（I）） = 0.1544, R （all data） = 0.0484, wR （all data） = 0.1692, completeness to theta = 25.000 being 99.0% and GOF = 1.179. There are two kinds of intermolecular hydrogen bonds and one kind of C-H……π weak interaction between adjacent molecules. Compound L can be used as a candidate for desirable devices with high performance due to its good thermal stability and excellent optical performance.
