In the title compound, [Zn(C11H7N6)2(H2O)2], the Zn(II) cation, located on an inversion center, is N,N'-chelated by two 5-(pyrazin-2-yl)-3-(pyridin-3-yl)-1,2,4-triazolide anions and is further coordinated by two water mol-ecules in a distorted N4O2 octa-hedral geometry. In the anionic ligand, the pyrazine and pyridine rings are twisted with respect to the central triazole ring by 5.77 (10) and ...

In this study, 1-(5-Methyl-1-(p-tolyl)-1H-1,2,3-triazol-4-yl)ethan-1-one, was reacted with Thiosemicarbazide, alkyl carbodithioate and benzaldehyde to give thiosemicarbazone, alkylidenehydrazinecarbodithioate and 3-phenylprop-2-en-1-one-1,2,3-triazole derivatives. The 1,3,4-thiadiazole derivatives containing the 1,2,3-triazole moiety were obtained via reaction of alkylidenecarbodithioate with h...

In this manuscript, a new series of 1,2,4-triazole-3-ones containing imin function was synthesized from 5-(4-bromobenzyl)-4-amino-2H-1,2,4-triazol-3(4H)-one and aromatic aldehyde by using microwave irradiation technique via schiff base reaction. Firstly, ethyl imido-p-bromophenylacetate hydrochloride (2) according to the pinner method in literature. Then, compound 2 reacted with carbazate p-bro...

1. A method is described for the estimation of thiol ester groups. The thiol ester is converted into the corresponding thiol by reaction with ammonia; the thiol is then titrated amperometrically with mercuric chloride. 2. The method may be used in the presence of SH and S.S groups. The SH groups are titrated at pH3 in the presence of excess of chloride; under these conditions thiol esters do no...

For the first time, 5-formyl-1-(pyridin-3-yl)-1H-1,2,3-triazole-4-carboxylate was synthesized via a two-step scheme. The molecular structure of compound determined by single-crystal X-ray diffraction analysis. Hirshfeld surface analysis used to study various intermolecular interactions. crystalline is marked presence three types ?-interactions (n??*, lp···?, and ?···?) between -C(H)=O group tri...

In the title compound, [Zn(C(4)HN(3)O(4))(H(2)O)(3)](n), each Zn(II) atom adopts a distorted octa-hedral coordination geometry, being surrounded by one chelating and one monodentate 1H-1,2,4-triazole-3,5-dicarboxyl-ate ligand and three water mol-ecules. Adjacent Zn(II) cations are linked by a 1H-1,2,4-triazole-3,5-dicarboxyl-ate ligand in a μ(2),κ(3) fashion to form a chain running along the c ...

The title compound, C11H11ClN4OS, crystallizes with two mol-ecules, A and B, in the asymmetric unit in which the dihedral angles between the triazole and benzene rings are 54.6 (3) and 56.0 (3)°. Both mol-ecules feature an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring. In the crystal, A-B dimers are linked by pairs of weak C-H⋯S hydrogen bonds along with π-π stacking inter-a...

In the title compound C(21)H(21)ClF(2)N(3)O(2) (+)·NO(3) (-), the triazole ring makes dihedral angles of 40.7 (3) and 30.2 (4)° with the 4-chloro-pheny and 2,4-difluoro-phenyl rings, respectively. The cation adopts a Z-configuration about the C=C double bond which links the triazole ring to the 4-chloro-phen-oxy unit via a but-yloxy chain. In the crystal, the cations and the anions are linked b...
