“…Azo dyes are an important class of organic chemicals containing at least one azo chromophore (-N=N-) which donors the color for this famous type of dyes [1]. They play essential role in academic and applied research [2]. Electronic and geometrical features of azo metal dyes induce redox, nonlinear optical and magnetic properties and these properties lead to increase the sensitivity and stability of these compounds towards optical data storage device [3,4].…”

In the present work azo dye ligand of 3-aminopyridine (L) and its complexes of NiII and CuII were synthesized, characterized and evaluated for antibacterial and antifungal activities in vitro. The L ligand was synthesized by reacting diazonium ion of 3-aminopyridine with 1-naphthole in presence of sodium acetate. The ligand (L) and its complexes were characterized by elemental analysis (CHN), magnetic susceptibility, molar conductivity, UV-Vis spectra, and infrared technique. The (L) azo dye exhibited high sensing for the pH changes. The color of L dye changed from red in basic medium to yellow color in acidic medium. The data of CHN, UV-Vis and magnetic susceptibility indicate that the complexes [Ni(L)2Cl2] and [Cu(L)2Cl2] are tetrahedral. The complexes of Ni(II) and Cu(II) exhibited potent activity against growth of Staphylococcus aureus and Escherichia Coli as well as against Penicillium Sp. And Aspergillus niger. Under visible irradiation (395 nm), the (L) azo dye of pyridine exhibited a significant change in the spectra under irradiation.

“…Azo dyes consider significant analytical reagents for the micro-estimation of metal ions. 1-(2-Pyridylazo)-2-naphthol considers well-known azo dye with term PAN which forms stable complexes with many metal elements [2]. In the same time, it is sensitive for trace concentration of metal elements and trace elements [5,6].…”

This scientific paper presents two novel lanthanide metal complexes [Sm (III) and Ce (IV)] synthesized through a series of reactions involving organic ligand 8-[3-(pyrazoyl)azo]adenine (PAA). Ligand (PAA) and their complexes were characterized using various analytical techniques, including C.H.N.S elemental analysis, magnetic measurement, X-ray diffraction, thermal analysis, SEM, (TGA) UV-Vis spectroscopy, FT-IR spectroscopy, and HNMR analysis. These techniques were employed to support the mode of binding and geometrical structure for ligand (PAA) and its Lanthanide (Ln) complexes. The FTIR and HNMR spectral results showed that (PAA) acts as neutral N,N-bidentate with [Sm (III) and Ce (IV)]. The geometric shape of the synthesized Ln-complexes is octahedral. Also, TGA was used to investigate the thermal behavior of ligand and its complex. The results showed that the ligand dissociated in three steps, while the complex dissociated in five steps. This indicates that the complex is more thermally stable than the ligand, likely due to the formation of strong coordination bonds between the ligand and the metal ions. These findings can contribute to the understanding of the thermal stability of metal complexes and inform the design of new metal-based materials with desirable properties. Finally, this paper examined the antibacterial, antifungal and anticancer activities of PAA and its complexes. The results indicated that all of these compounds exhibited significant activity against bacterial and fungal pathogens, as well as cancer cells.

In the current work, the azo ligand and its Pd (Ⅱ), Cd (Ⅱ), Zn (Ⅱ) and Hg (Ⅱ) complexes were synthesized, characterized and their spectroscopic characteristics were studied. The new ligand was synthesized from the coupling reaction between 4,5-bis(4-methoxy phenyl)imidazole and the diazonium salt of 4-Amino benzoic acid in an alkaline medium at 0-5 ᵒC. the new azo metal complexes were prepared by the reaction between the ligand and metals chlorides. All the synthesized compounds were characterized by FT-IR, 1H-NMR, Mass spectral analysis, UV-Vis spectrophotometric, molar conductivity, and magnetic sensitivity. The biological activity of the azo ligand and its Pd (Ⅱ) complex was also studied. keywords: Azo compound, 4,5-di (4-methoxy phenyl) imidazole, azo metal complexes
