In the mol-ecule of the title compound, C(18)H(19)N(3)O(3), the triazole ring is oriented with respect to the 3-methoxy-phenyl and 2-methoxy-phenyl rings at dihedral angles of 11.79 (3) and 89.22 (3)°, respectively. The dihedral angle between the two benzene rings is 85.95 (3)°. In the crystal structure, inter-molecular O-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules. There is a π-π contact ...

The synthesis of 3-amino-1-nitroguanidine (3-ANQ) and 5-hydrazino tetrazole (5-HT) derivatives as new energetic materials are described. Reaction of 3-ANQ with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-HT. Addition of NaN3 to a mixture of 3-ANQ and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excelle...

Recently, we have enatiospeciflcally synthesized nagstatin (1) and its analogs (for example, 2) having different configurations and functionalities and clarified the structure-activity relationships2 ~ 4). Herein, we describe the synthesis of the triazole analogs (3 and 4) having a triazole ring in place of an imidazole ring, and evaluate their glycosidase inhibitory activities to better unders...

The title compound, C(20)H(12)Cl(3)N(3)O(2), was synthesized by the reaction of 2-(2-hydroxy-phen-yl)benz[e][1,3]oxazin-4-one with 2,4,6-trichloro-phenyl-hydrazine in ethanol. The trichloro-phenyl ring is nearly perpendicular to the triazole plane [dihedral angle 80.56 (8)°], whereas the two hydroxy-phenyl rings are approximately coplanar with the triazole ring [dihedral angles of 2.79 (12) and...

The title compound, C(9)H(10)N(4)S·0.095H(2)O, consists of discrete 4-ethyl-3-(3-pyrid-yl)-1H-1,2,4-triazole-5(4H)-thione mol-ecules and a disordered mol-ecule of water of hydration with partial occupancy, lying on a twofold rotation axis. The dihedral angle between the pyridine and triazole rings is 41.73 (8)°. In the crystal structure, mol-ecules are hydrogen bonded via triazole NH groups and...

This paper reports on the synthesis and characterization of two Schiff bases bearing 1,2,4-triazolic moieties, namely 4H-4-(2-hydroxy-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole and 4H-4-(4-nitro-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole using thin layer chromatography, melting interval, elemental analysis, spectroscopy and thermal stability studies.

In the title one-dimensional coordination polymer, [Ag2(NCS)2(C3H5N3S)2] n , the Ag(I) atom adopts a distorted tetra-hedral AgNS3 geometry. Adjacent Ag(I) atoms in the [001] chain are alternately linked by pairs of bridging 4-methyl-1H-1,2,4-triazole-3(4H)-thione (Hmptrz) ligands (via their S atoms) and double thio-cyanate bridges linking through both S and N atoms (μ-1,3-SCN). An intra-chain N...

Heterocyclic 1,2,4-triazole derivatives possess unusually spacious potentiality as medicinal agents, agricultural chemicals, functional materials, ionic liquids, supramolecular catalysts as well as artificial enzymes and receptors for supramolecular recognition and biomimetic catalysis, and their various researches and developments have been being a quite rapidly developing and active highlight...
