A Schiff base was synthesized by 3-methyl-4-amino-5-ethoxycarbonyl-methylsulfanyl-1,2,4-triazole with 3-nitrobenzaldehyde. The structure was confirmed by 1H NMR, IR, H RMS, TGA techniques and X-ray diffraction. The crystal belongs to monoclinic system, space group P21/c, with a = 8.965(2), b = 21.903(5), c = 9.197(2) A, β = 114.011(4)°, C14H15N5O4 S, Mr = 349.08, V = 1649.7(6) A3, Dc = 1.407 g·cm-3, Z = 4, F(000) = 728, μ = 0.226 mm-1, the final R = 0.0574 and wR = 0.1336 for 2932 unique reflections with I > 2σ(I). Furthermore, the biological activity to four vegetable pathogens has been tested. The title compound exhibits better biological activity to four vegetable pathogens compared to the Schiff base without 5-ethoxycarbonyl and to Gibberlla saubinetti in EC95 compared with triadimefon.
