“…The spectra of the complexes showed a broad band at frequencies of 3425-3188 cm -1 , which are attributed to the symmetric and asymmetric vibrations of the N-H bond [28]. However, they were not observed in the spectrum of the ligand, which indicated that the ligand was coordinated with the metals through the azo group to form an M-N bond at 426-441 cm -1 in addition to the weak band at 532-580 cm -1 that was attributed to the M-O bond [29]. A broad band at 3410 cm -1 appears in the free ligand is attributed to the OH group of 8-hydroxy quinolone.…”

ABSTRACT. An azo quinoline ligand, (E)-2-((4-iodophenyl)diazenyl)-8-hydroxyquinoline (IPDHQ), was synthesized by the coupling reaction of 4-iodoaniline diazonium salt with 8-hydroxyquinoline. The synthesized ligand and its Cd(II), Pd(II), Cu(II) and Hg(II) complexes were spectrally characterized by UV‒Vis spectrophotometry, FT-IR, mass spectral analysis, 1H-NMR, magnetic sensitivity and molar conductivity. The general formula of the Cd(II), Cu(II) and Hg(II) complexes is [M(L)2].Cl2.H2O with octahedral geometry, while the general formula of the Pd(II) complex is [M(L).Cl2].H2O with square planer geometry. A simple and rapid spectrophotometric procedure was suggested for the determination of Hg(II) using the synthesized ligand as a spectrophotometric reagent. By measuring the absorbance for the resulting orange complex at 430 nm, the linearity range was 0.5-15 µg mL-1, and the interfering effect was also studied. The synthesized azo ligand and its Hg(Ⅱ) complex were tested for their biological activity against four bacterial strains.

A sensitive and accurate Sequential Injection Analysis technique for determining Cupper (II) ion in different samples, using a new azo derivative reagent of 8-hydroxy quinoline (HQDABA). The reagent and Cu(II) complex diagnosis included Infrared spectroscopy, Ultraviolet-Visual radiation, Elemental Analysis (CHN), Energy dispersive X-ray spectroscopy (EDX), nuclear magnetic resonance spectroscopy 1HNMR and mass spectroscopy techniques. The method depends on the reaction of Cupper (II) with the (Azo derivative of 8-hydroxy Quinoline) reagent in a neutral medium to form a Brown complex which gave a maximum absorbance at 420 nm. The optimum conditions such as flow rate, Copper (II) volume, reagent volume; pH, reagent concentration, and reaction coil length are thoroughly examined. A Copper (II) curve is constructed, and the suggested method obeys Beer's law over ration range of 1-10 mg/ L. The limits of detection (LOD) and on (LOQ) are determined to be (0.361) mg/ L and(1.204) mg/ L, while Sandell's sensitivity and molar absorption coefficient are to be (0.120) µg/ cm2 and (527.05) L/ mol. cm respectively. The recommended method has given good accuracy with recovery rates ranging from (77.82% - 115% ).

Heterocyclic azo compound 2-(8-quinolyl azo)-4,6-dimethyl phenol as a primary ligand and imidazole molecule as a secondary ligand in the basic medium were prepared with novel mixed ligand complexes of Hg(II), Mn(II), Ni(II), Co(II) and Cu(II) ions, these compounds were characterized by Mass, 1HNMR, IR, UV-Vis, Magnetic susbtibility and Molar Conductivity, which suggested octahedral conductivity. Free ligands and five mixed ligand complexes of Hg(II), Mn(II), Ni(II), Co(II) and Cu(II) metal ions with a general formula of [M(L1)(L2)2C1] against eight pathogenic multidrug resistance bacteria, six G-ve bacteria (Pr. mirabilis, S. typhi, E. coli, P. aeroginosa, A. baumanii and K. pneumoniae) and two G+ve bacteria (E. faecalis and S. aureus) were capable of antimicrobial efficacy. The findings show that free ligands have had stronger antibacterial activity on S. Bacterial isolation of typhi and P. aeroginosa relative to other isolates. As for the effectiveness of metal complexes, compared to G+ve bacteria, they usually have a large antibacterial effect on G-ve bacteria, whereas the Hg(II) ion complex has a higher antibacterial effect on most bacterial isolates compared to other metal complexes. Compared with other metal complexes, Mn (II) ion complexes demonstrated poorer antibacterial activity..
