“…This attention comes because of their straightforward synthetic methods and diverse potential applications as, for example, antimicrobial, [1,2] antitumor, [3,4] antioxidant, [5] antimalarial, [6] antitubercular, [7,8] antihypertensive, [9] agents. In addition, hydrazones are employed in catalytic processes, [10,11] wastewater treatment, [12,13] and other fields. [14,15] Triazine-based ligands have attracted special interest as a result of the importance of these heterocyclic compounds and their various applications, including biological, pharmaceutical, [16][17][18][19] and industrial [20] applications.…”

New mononuclear Fe (III), Cu (II), Ag (I), ZrO ( IV) and UO2(VI) complexes were synthesized by the reaction of metal ions with (E)‐3‐(2‐(5, 6‐ diphenyl‐1,2,4‐ triazin‐3‐ yl)hydrazono)butan‐2‐ one oxime. The structures of the metal complexes were characterized using analytical, spectral (infrared, electronic, 1H NMR, electron spin resonance (ESR), and mass), magnetic moment, molar conductance, thermal gravimetric analysis, and powder X‐ray diffraction (XRD) measurements. All complexes have octahedral geometries except the Cu (II) complex, which has square planar geometry, and the UO2(VI) complex, in which the coordination number is seven. The ligand acts as a (neutral, monoanionic or dianionic) tridentate with N2O coordinating sites: N‐azomethine, N‐triazine, and O‐oxime. Fluorescence spectral studies were carried out in solid state and in dimethylformamide (DMF). The kinetic parameters of the thermal decomposition stages were calculated using Coats–Redfern equations. The morphological structures of the ligand and some complexes were determined using XRD. The molecular orbital calculations were carried out for the ligand and metal complexes using the Hyperchem 7.52 program on the basis of the PM3 level. The antimicrobial activities of the ligand and its complexes were investigated towards the microorganisms S. aureus and B. subtilis as Gram‐positive bacteria, S. typhimurium and E. coli as Gram‐negative bacteria, C. albicans, and A. fumigatus. The ligand and its complexes showed antitumor activity against Hep G‐2 cell lines, where Cu (II) and Ag (I) complexes seem to be promising as they showed IC50 values that are lower than and comparable to that of the antitumor drug doxorubicin.

“…They have found some applications such as extraction and spectrophotometric determination of metal ions [1][2][3] and spectrophotometric determination of some species in pharmaceutical formulations [4], as well as uses in catalytic processes [5,6] and wastewater treatment [7]. Hydrazones and their complexes have shown significant activity against several kinds of tumors, for example isonicotinoyl hydrazone derivatives and their iron(III) complexes showed good activity against certain mammary tumors and leukemia in mice [8,9].…”

A hydrazone ligand (HL) containing the thiophene moiety has been prepared via condensation of thiophene-2-carbohydrazide with 1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carbaldehyde. The complexes of copper(II), nickel(II), cobalt(II), manganese(II), zinc(II), palladium(II), iron(III), ruthenium(III), uranyl(VI), and titanium(IV) with the ligand were prepared in good yield from the reaction of the ligand with the corresponding metal salts. The ligand and complexes were characterized using infrared, mass spectra, nuclear magnetic resonance, electronic absorption spectra, electron spin resonance, and magnetic moment measurements as well as elemental and thermal analyses. The results showed that the complexes are enolic by nature, whilst the ratio between the metal ion and the ligand depends on the acidity of the metallic ions and their oxidation numbers.

“…Hydrazones play an important role in improving the antitumor selectivity and toxicity profile of antitumor agents by forming drug carrier systems employing suitable carrier proteins [11]. They are also employed as extracting agents in spectrophotometric determination of some ions [12][13][14] and spectrophotometric determination of some species in pharmaceutical formulations [15], as well as used in catalytic processes [16,17] and waste water treatment [18]. Hydrazones, such as pyridoxal isonicotinoylhydrazone, salicyladehyde benzoylhydrazone and 2-pyridyl carboxaldehyde-2-thiophene carboxaldehyde hydrazone, act as orally effective drugs for the treatment of iron overload diseases or genetic diseases b-thalassemia [19,20].…”

a b s t r a c tFT-IR spectrum of quinoline-2-carbaldehyde benzoyl hydrazone (HQbÁH 2 O) was recorded and analyzed. The synthesis and crystal structure data are also described. The vibrational wavenumbers were examined theoretically using the Gaussian03 package of programs using HF/6-31G(d) and B3LYP/6-31G(d) levels of theory. The data obtained from vibrational wavenumber calculations are used to assign vibrational bands obtained in infrared spectroscopy of the studied molecule. The first hyperpolarizability, infrared intensities and Raman activities are reported. The calculated first hyperpolarizability is comparable with the reported values of similar derivatives and is an attractive object for future studies of non-linear optics. The geometrical parameters of the title compound obtained from XRD studies are in agreement with the calculated values. The changes in the CAN bond lengths suggest an extended p-electron delocalization over quinoline and hydrazone moieties which is responsible for the non-linearity of the molecule.
