Two 3-D and one 2-D metal-organic frameworks [Cu(8)I(8)(L1)(4)](n) (1), [Cu(8)I(8)(L2)(4)](n) (2) and [Cu(4)I(4)(L3)(2)](n) ()3 were synthesized using three novel pyridine and pyrazole supported 1,2,3-triazoles, 1-(4-picolyl)-4-butyl-1H-1,2,3-triazole (L1), 1-(4-picolyl)-4-pentyl-1H-1,2,3-triazole (L2) and 1-(4-picolyl)-4-(3,5-dimethylpyrazolylmethyl)-1H-1,2,3-triazole (L3). In both complexes 1...
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...
Triazoles are known for their non-toxicity, higher stability and therapeutic activity. Few nucleoside (L1, L2 and L3) and non-nucleoside 1,2,3-triazoles (L4-L14) were synthesised using click chemistry and they were screened for tumor cell cytotoxicity and proliferation. Among these triazole ligands studied, nucleoside ligands exhibited higher potential than non-nucleoside ligands. The nucleosid...
In the title compound, C(19)H(17)N(3)O, the triazole and benzene rings adopt a Z configuration with respect to the C=C bond. The phenyl and benzene rings form dihedral angles of 66.20 (9) and 14.36 (9)°, respectively, with the triazole ring. The dihedral angle between the phenyl and benzene rings is 52.64 (8)°.
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)°.
A pair of new anticancer nucleosides based on 1,2,4-triazole nucleosides and 1-((2-hydroxyethoxy) methyl)-5-(phenylthio)-1H-1,2,4-triazole-3-carboxamide have been synthesized, and have given the corresponding products in excellent yields. Its structures and conformations were confirmed by single crystal X-ray diffraction.
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.
Acetylation with acetic anhydride of methyl 5-amino-1H-[1,2,4]triazole-3-carboxylate, one of the hetareneamino acids, was studied using HPLC, H NMR, FTIR and GC-MS. The compound has a significantly decreased susceptibility to acetylation compared to 5-amino-1H-[1,2,4]triazole itself. Two isomeric diacetylated products were found.
