The title compound, C10H10N4OS, is nearly planar with the mean planes of the hy-droxy-benzyl and triazole rings inclined at an angle of only 3.2 (7)°. In the crystal, O-H⋯N hydrogen bonds between the hy-droxy group and the triazole ring in concert with weak N-H⋯S inter-molecular inter-actions between the triazole ring and thione group form chains along [-210] enclosing R 2 (2)(8) graph-set moti...

New 1,4- and 2,4-substituted 1,2,3-triazole derivatives were synthesized and tested as potential BK(Ca) channel openers, as a part of a research program, which hypothesizes a pharmacophoric structure containing the 1,2,3-triazole ring. The structure-activity relationships were studied introducing some structural changes concerning molecular geometry and the presence of a hydrogen bond donor as ...

In the title compound, C(8)H(9)N(5), a Schiff base derived from N-methyl-pyrrole-2-carbaldehyde and 3-amino-1,2,4-triazole, the C=N double bond linking the two aromatic rings has a Z conformation. The two rings are twisted by 24.20 (5)°. A chain motif results from N-H⋯N hydrogen bonding.

In the title compound, C18H14N4O2, the triazole ring makes dihedral angles of 77.32 (8) and 75.56 (9)°, respectively, with the indoline residue and the terminal phenyl group. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds into tapes parallel to the b axis. The tapes are linked together by π-π inter-actions between triazole rings [inter--centroid distance = 3.4945 (9) Å].

In the title compound, C(20)H(16)N(4)O(2), the benzene rings of the 2-hydroxy-phenyl and 4-methoxy-lphenyl groups form dihedral angles of 64.02 (8) and 77.39 (7)°, respectively, with the mean plane of the triazole ring. The dihedral angle between the triazole ring mean plane and the pyridyl ring is 9.61 (8)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into zigzag c...

In the title compound, C(14)H(10)N(6)O(2)S, the dihedral angle between the pyridine and triazole rings is 3.21 (10)°. The mol-ecule is significantly twisted about the N(t)-N(b) (t = triazole and b = benzyl-idene) bond [C-N(t)-N(b)=C = 151.64 (17)°]. In the crystal, mol-ecules are linked by weak N-H⋯N hydrogen bonds, generating C(8) chains propagating in [10[Formula: see text]].

The title compound, C(8)H(8)N(6)O, was obtained by the reaction of 3,5-diamino-1,2,4-triazole with ethyl 2-picolinate in a glass oven. The dihedral angles formed between the plane of the amide group and the pyridine and triazole rings are 11.8 (3) and 5.8 (3)°, respectively. In the crystal, an extensive system of classical N-H⋯N and N-H⋯O hydrogen bonds generate an infinite three-dimensional ne...

In the title mol-ecule, C(30)H(23)N(5)O(3)S, the 1,2,4-triazole ring is approximately planar (r.m.s. deviation = 0.006 Å), and forms dihedral angles of 66.0 (2), 65.1 (2), 30.1 (2) and 28.1 (2)° with the four phenyl rings. The phenyl ring of the benzyl group directly attached to the triazole ring is almost perpendicular to the nitro-phenyl ring, making a dihedral angle of 84.9 (2)°.
