The title compound C18H16N4O2S has been synthesized by the reaction of 4-amino-3-(4-ethoxyphenyl)-5-mercapto-1,2,4-triazole with phenoxyacetic acid in phospho- rus oxychloride, and characterized by IR, NMR spectra and elemental analysis. Its structure was determined by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 1.4903(3), b = 1.5230(2), c = 0.9615(16) nm, Z = 4, V = 1.7769(5) nm3, Dc = 1.317 g/cm3, μ = 0.201 mm-1, F(000) = 736, R = 0.0795 and wR = 0.2233. In the title compound, all rings are essentially planar.
