“…The spectral data and the magnetic moment of prepared metal complexes are presented in Table- ) may be assigned n→π* charge transfer transition due to presence conjugation in the imidazole ring [33,40].The electronic spectrum of the Cr(III) complex displayed bands at 240 nm (41667 cm -1 ) and 480 nm (20833 cm -1 ). These two bands are assignable to center ligand and 4 A2g→ 4 T1g(F) transitions respectively in an octahedral environment [24,34].…”

“…The signal at δ = 2.505-2.513 ppm (S, 3H) due to the presence of CH 3 group. While a signal at δ = 1.151-1.238 ppm (S) due to solvent protons [32,33]. The 1 H NMR spectrum of Ni(II) complex shows a signal at δ = 10.046 ppm (S, 1H) due to the presence of amide (NH) proton in imidazole molecule while a signal at δ = 10.023 ppm (S, 4H and 5H) proton due to imidazole ring.…”

“…The strong band at 1645 cm -1 in the free ligand was attributed to ν(C=N) of the imidazole ring (N3). This band shifts to lower wave number side (1542, 1605) cm -1 in all metal complexes indicating the coordination [24,33]. The sharp band at 1468 cm -1 is characteristic of the azo group ν(-N=N-) in the free ligand.…”

Asian Journal of Chemistry; Vol. 30, No. 2 (2018), 280-292 in the azo dyes compounds, such as hydroxyl, carboxylic acid, halogens, esters and amines [19,20]. An important uses of azo imidazole compounds used analytical reagents for solvent extraction to determination of some metal ions [21,22]. The heterocyclic azo imidazole compounds have important role in spectral determination field to determine the trace amount of elements especially transition metal ions and heavy metals because of high sensitivity and selectivity [23,24].The present work describes the synthesis and spectral characterizations of 2'[2'-(1-hydroxy-4-methyl phenyl)azo]-imidazole (HMePAI = HL), containing phenolic-OH function and imidazole moiety. The heterocyclic mono azo dye ligand and its metal complexes were studied by various spectral analysis and screened for their biological activities. As well as the study of ligand and Ni(II) complex of prescription drug anticancer by using the lines of cancerous liver cells of the type HePG2 and compared with line of the ordinary cells.

In this paper we report the synthesis and identification of Ni(II), Cu(II) and Zn(II) complexes with new thiazole based azo dye 2-[2'-(5-methyl thiazolyl)azo]-5-dimethyl amino benzoic acid (5-MeTAMB) by the diazotization of 2-amino-5-methyl thiazole and coupling with 3-dimethyl amino benzoic acid in alkaline alcoholic solution. The structures of the azo dye ligand and its metal complexes were confirmed by various analytical techniques like by elemental analysis (C.H.N.S), UV-visible, FT-IR spectroscopic, mass spectroscopic, Asian Journal of Chemistry; Vol. 30, No. 7 (2018), 1537-1545 microbial activities such as antibacterial [17], antiviral [18] and antifungal [19]. In this work describe the preparation and characterization of new thiazolylazo ligand (5-MeTAMB) and its complexes with Ni(II), Cu(II) and Zn(II) ions, is described biological activities (antibacterial and antifungal). The thiazolylazo ligand and its Cu(II) complex evaluated for in vitro anticancer activity against human breast cancer MCF7 by MTT assay. EXPERIMENTALAll the chemicals and solvents were of the highest purity obtained from BDH, Aldrich, sigma and Merck. Mass spectra was obtained using a Shimadzu Agilent Technologies 5973C at 70 e and MSD energy using a direct insertion probe (Acq method 10 W energy) at temperature 90-110 °C.

A novel azo dye ligand was created by diazotizing 4‐aminoantipyrine and then coupling it with 2‐aminophenol as part of a methodical investigation of physiologically active compounds, 4‐aminoantipyrine. The novel complexes containing Cr(III), Fe(III), Mn(II), Co(II), Ni(II), Zn(II), Cu(II), and Cd(II) were created from the target ligand (L). The structures of the ligand and metal complexes were verified by elemental analyses, thermogravimetric analysis–difference thermogravimetry (TGA‐DTG), conductivity measurements, infrared (IR), UV–Vis, 1H‐nuclear magnetic resonance (NMR), X‐ray diffraction (XRD), and mass spectrometry. Using the Gaussian 09 tool, the density functional theory (DFT)/B3LYP method was utilized to compute the energy gaps and other important theoretical features. Also, the newly synthesized azo dye ligand, in comparison with metal complexes, was screened for its antimicrobial activity. The crystal structures of Staphylococcus aureus and Bacillus subtilis as gram‐positive bacteria, Salmonella sp. and Escherichia coli as gram‐negative bacteria, and fungal (Aspergillus fumigatus and Candida albicans) species were compared with the produced azo dye and its metal complexes via molecular docking. Most of the complexes exhibited greater antimicrobial activities against these organisms than did the original azo dye ligand.
