| Abstract: | The crystal structure of the title compound 3-(4-Chloro-3-ethyl-1-methyl-1H-pyrazol-5-yl)-6- (E) phenylvinyltriazolo 3, 4-b ]-1, 3, 4-thiadiazole ( C17 H15ClN6S, Mr = 370.87) was determined by single crystal X-ray diffraction. The crystal ismonoclinic, space group P21/n, a = 10.862(2), b = 11.541(2), c = 14.994(3) A,β=108.41(3)°, V=1783(1) A, Z=4, Dx =1.381g/cm-3, μ=0.3361 mm-1, andF(000) = 768. The results confirmed that the title compound belongs to type E of ste-reochemistry. The dihedral angle between triazole and 1, 3, 4-thiadiaole ring is 3° andthe torsion angle between 1,3, 4-thiadiazole and pyrazole ring is 134.0°. |
