The crystal structure of 4-phenyl-5-(1-t-butyl-5-methyl-4-pyrazolyl)-1,2,4-triazol- 3-thione 5 (C16H19N5S, Mr = 313.42) has been determined by single-crystal X-ray diffraction analysis. The crystal belongs to monoclinic, space group P21/c with a = 6.680(2), b = 27.44(1), c = 9.388(4) ? b = 106.738(6), V = 1648(1) 3, Z = 4, Dc = 1.263 g/cm3, m = 0.200 mm-1, F(000) = 664, R = 0.0608 and wR = 0.1176. The results confirmed that 5 can be assigned to the thione tautomeric form. 展开更多

The crystal structure of 5-nitro-4-salicylideneamino-3-methyl-1,2,4-triazole-5-thione ([C 10 H 9N 5O 3S]·HCON(CH 3) 2, M r=352.38)(CCDC No. 216094) was determined by the single crystal X-ray diffraction... The crystal structure of 5-nitro-4-salicylideneamino-3-methyl-1,2,4-triazole-5-thione ([C 10 H 9N 5O 3S]·HCON(CH 3) 2, M r=352.38)(CCDC No. 216094) was determined by the single crystal X-ray diffraction method. The crystal belongs to a triclinic system, the space group is P1 with unit cell constants a= 0.6113(2) nm, b=1.0836(4) nm, c=1.3132(5) nm, α=74.523(7)°, β=117.68(3)°, γ= 79.769(7)°, V=0.8245(5) nm 3, Z=2, D c=1.419 g/cm 3, μ=0.228 mm -1 , F(000)=368, R and wR are 0.0579 and 0.1040, respectively, beasd on 3348 unique reflections of which 1925 reflections were observed[I>2σ(I)]. The results indicate that the title compound can be assigned to the thione tautomeric form rather than the thiol tautomeric form. It contains a five membered triazole ring and a phenyl ring with a dihedral angle of 4.35°. The intermolecular hydrogen bond N3_H3…S1, O1_H1…O4 can be observed. 展开更多
