摘要
A novel Schiff base was synthesized via 5-benzyl-4-amino-1,2,4-triazole-3-thione with 3-phenoxy-benzaldehyde under refluxing. The structure was characterized by elemental analysis, IR, 1H NMR, ESI-MS and single-crystal X-ray diffraction. This compound crystallizes in monoclinic, space group P21 /c with a = 16.0289（16）, b = 5.8022（6）, c = 20.542（2）, β = 95.667（2）o, C22 H18 N4 OS, Mr = 386.46, V = 1901.1（3）3, Z = 4, Dc = 1.347 g/cm3, F（000） = 804, μ = 0.191 mm-1, the final R = 0.0453 and wR = 0.1307 for 2456 observed reflections with I 〉 2σ（I）. The crystal packing of the compound is stabilized by classical intermolecular N–H…S hydrogen bonds. Furthermore, the biological activity to four vegetable pathogens has been tested. The title compound exhibited good fungicidal activities to Gibberlla nicotiancola.
