In the title mol-ecule, C(17)H(10)F(3)N(3)O, the C=C bond connecting the triazole ring and 4-fluoro-phenyl groups adopts a Z conformation. The triazole ring forms dihedral angles of 15.3 (1) and 63.5 (1)°, with the 2,4-difluoro-substituted and 4-fluoro-substituted benzene rings, respectively. The dihedral angle between the two benzene rings is 51.8 (1)°.

Complexes of 1,2,4-triazole (trz) and of the 1,2,4triazolate ion (trz') have been described before. Most of the papers dealt with copper compounds, especially CuCl2(trz), CuCl(trz')(H20 ) 2 and Cu(trz')2 1_n. J a r v i s 12 determined the structure of CuCl2(trz). It is a polynuclear complex, the copper ions being bridged by two chloride ions and a 1,2-bicoordinating triazole ligand. The linear ...

New 1,3,4-thiadiazole, 6, 7 and 1,2,4-triazole derivatives, 8, 9 containing a phenylalanine moiety have been synthesized by intramolecular cyclization of 1,4-disubstituted thiosemicarbazides, 4, 5, in acid and alkaline media, respectively; the thiosemicarbazides were obtained by reaction of hydrazide 3 with appropriate aromatic isothiocyanates. The toxicity of the synthesized compounds was eval...

A one-pot three-component [2+3] cycloaddition for the synthesis of 1-alkyl 1H-naphtho[2,3-d][1,2,3]triazole-4,9-dione and 2-alkyl 2H-naphtho[2,3-d][1,2,3]triazole-4,9-dione has been developed. By taking the advantage of difference in basicity, both products can be obtained in good purity. The unique heterocyclic scaffolds of these two products could exert interesting chemical and biological pro...

Betulinic acid, BA, is a lupane derivative that has caught the interest of researchers due to wide variety pharmacological properties it exhibits towards tumor cells. Because their prospective increased anti−proliferative efficacy and improved profile, BA derivatives continue be described in scientific literature. The current work was conducted order determine antiproliferative activity, under ...

In the title mol-ecule, C(7)H(7)N(5)S, the pyridyl and triazole rings form a dihedral angle of 20.07 (6)°. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains extended in the direction [10]. Further stability is provided by π⋯π stacking inter-actions, indicated by short distances between the centroids of triazole rings [3.480 (5) Å] and pyridyl rings [3.574 (5) Å] of neighbouri...

Some 3-(Substituted methylthio)-4-phenyl-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole derivatives were synthesized in six steps starting from easily accessible gallic acid. The resulting sulfides were then catalytically oxidized to the title sulfones with H2O2. The products were obtained in high yield under mild conditions and practically devoid of any by-products. The structures were confirmed...

In the title compound, [Zn(2)I(4)(C(4)H(8)N(4))(2)], the Zn(II) atom is coordinated in a distorted tetra-hedral geometry by two N atoms from the triazole rings of two 4-amino-3,5-dimethyl-4H-1,2,4-triazole (admt) ligands and two iodide ligands. Doubly bridging admt ligands connect two Zn(II) atoms, forming a centrosymmetric dimer. Weak N-H⋯I and C-H⋯I hydrogen bonds play an important role in th...

The title compound, [Co(C(2)H(2)N(3))(C(7)H(3)N(2)O(6))](n), was obtained by the reaction of CoCl(2), triazole and 3,5-dinitro-benzoic acid in a 1:1:1 ratio. The Co centre is in a distorted tetrahedral coordination by three N atoms of three different triazole ligands and one O atom of the 3,5-dinitrobenzoate anion.

In the title compound, C(16)H(17)N(3)O(2)S·H(2)O, the triazole ring makes a dihedral angle of 34.63 (6)° with the benzene ring. The thio-phene ring is disordered over two orientations [occupancy ratio = 0.634 (4):0.366 (4)] which make dihedral angles of 54.61 (16) and 54.57 (31)° with the triazole ring. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds stabilize the crystal structure.
