In the title Schiff base, C(8)H(8)N(4)S, a condensation product of 5-methyl-thio-phene-2-carboxaldehyde and 3-amino-1,2,4-triazole, the dihedral angle between the triazolyl and thienyl rings is 6.44 (14)°. The compound exists as a polymeric chain arising from inter-molecular N-H⋯N bonding.

In the title mol-ecule, C(9)H(10)N(4)S, the dihedral angle between the benzene and triazole rings is 81.05 (5)°. In the crystal, N-H⋯N hydrogen bonds link the mol-ecules into infinite zigzag chains along [010].

In the title compound, C(30)H(24)N(4)O(2)S, the four phenyl rings of the substituent groups make dihedral angles of 88.1 (2), 81.0 (2), 21.4 (2) and 44.6 (2)° with the triazole group. An intra-molecular hy-droxy-imino O-H⋯N hydrogen bond results in the formation of an approximately planar (r.m.s deviation = 0.0230 Å) six-membered ring.

In the title compound, C(12)H(11)F(2)N(3)O(2), the dihedral angle between the triazole and phenyl rings is 73.74 (9)°. In the crystal, mol-ecules are linked into chains along [010] via weak C-H⋯O and C-H⋯N hydrogen bonds.

The structures of three 3-methyl-1H-1,2,4-triazole-5-thione derivatives are reported. The structure of 4-amino-3-methyl-1H-1,2,4-triazole-5(4H)-thione, C3H6N4S, (I), has been redetermined with an improved model for the H atoms: the non-H atoms of (I) all lie on mirror planes in space group Pbcm, and the H atoms of the methyl group are disordered over two sets of reflection-related atomic sites ...

Novel series of triazole-benzoxazole hybrid compounds (7a-7i) have been synthesized via click chemistry between different azide derivatives and benzoxazole terminal alkynes bearing an S-methylene linkage. The starting alkyne was prepared base-catalyzed S-alkylation substrate in two-step procedures. All the intermediates final products were fully characterized by 1D NMR, IR, mass spectrometry, e...

In the title complex, [Cd(C13H8N5)2(C2H5OH)2], the Cd(II) cation is located on an inversion center and coordinated by two deprotonated 2-(1H-benzotriazol-1-yl)-1H-benzimid-azol-1-ide (L) ligands and two ethanol mol-ecules in a distorted N4O2 octa-hedral geometry. In the L ligand, the dihedral angle between benzoimidazole and benzotriazole ring systems is 10.8 (3)°. In the crystal, the complex m...

The asymmetric unit of the title compound, C8H9N5O2, contains two independent mol-ecules (A and B) in which the dihedral angles between the triazole and pyrazole rings are 4.80 (14) and 8.45 (16)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into supra-molecular independent A and B chains propagating along the b-axis direction. The crystal structure also features π-π stacking ...

In the mol-ecule of the title compound, C(17)H(16)BrN(3)O, the triazole ring is oriented at dihedral angles of 6.14 (9)° and 82.08 (9)°, respectively, with respect to the phenyl and bromo-benzene rings. The dihedral angle between the bromo-benzene and phenyl rings is 87.28 (7)°. The intra-molecular C-H⋯O hydrogen bond results in the formation of a planar five-membered ring, which is oriented at...

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 ...
