4-[(5-Bromo-2-hydroxybenzylidene)amino]-3-propyl-1H-1,2,4-triazole-5(4H)-thione
The asymmetric unit of the title compound, C(12)H(13)BrN(4)OS, contains two independent mol-ecules in which the dihedral angles between the triazole and benzene rings are 2.9 (3) and 7.5 (3)°. The thione group is of the form R(2)C=S. An intra-molecular O-H⋯N hydrogen bond occurs in each mol-ecule. The crystal structure features weak N-H⋯S inter-actions and π-π stacking of the benzene rings [cen...

The title compound, C11H11BrN4OS, crystallized as a racemic twin with two symmetry-independent mol-ecules in the asymmetric unit. The dihedral angles between the benzene and triazole rings of the two independent mol-ecules are 56.41 (18) and 54.48 (18)°. An intra-molecular O-H⋯N hydrogen bond occurs in each mol-ecule. In the crystal, pairs of symmetry-independent mol-ecules are linked by pairs ...

In the title compound, C(8)H(6)N(4)O(2)S, the 1,2,4-triazole ring and the nitro group form dihedral angles of 6.26 (13) and 9.5 (3)°, respectively, with the phenyl ring. In the crystal, the mol-ecules are linked via pairs of N-H⋯S hydrogen bonds, generating [010] chains which contain R(2) (2) (8) ring motifs. The crystal structure is further stabilized by π-π stacking [centroid-centroid distanc...
متن کامل3-Benzyl-4-ethyl-1H-1,2,4-triazole-5(4H)-thione
The title compound, C(11)H(13)N(3)S, exists in the 5-thioxo tautomeric form. The benzene ring exhibits disorder with a refined ratio of 0.77 (2):0.23 (2) for components A and B with a common bridgehead C atom. The 1,2,4-triazole ring is essentially planar, with a maximum deviation of 0.002 (3) Å for the benzyl-substituted C atom, and forms dihedral angles of 88.94 (18) and 86.56 (49)° with the ...
