AZO complexes synthesized by binding metal ions as Mn(II), Co(II), Ni(II) and Cu(II), with the ligand (L) [ethyl 4-((E)-(5-oxo-1-(((1E,2E)-3-phenylallylidene)amino)-2-thioxo-2,5-dihydro-1H-imidazol-4-yl)diazenyl)benzoate] was prepared from three steps ,first step preparation Schiff base product of condensation reaction by reaction Thiosemicarbazide with cinnamaldeyde, second step preparation the Imidazole ring close by reaction ligand 1 with chloroethylacetate, finally preparation Azo ligand(Diazanium compound) by reaction ligand 2 with benzocain. Characterized the ligands and complexes in their solid state using the elemental micro analysis (C.H.N.S), flame atomic absorption. UV-vis spectroscopy, FT-IR, magnetic susceptibility measurements, Mass spectrum, 1H-NMR spectra and electrical molar conductivity. These techniques produced comparable results with those obtained for the solid complexes. From the data of all techniques, octahedral geometry was proposed for Mn(II), Co(II), Ni(II) and Cu(II) complexes.

... The v(N-H) vibration of the imidazole ring at 3417 cm -1 in the spectrum of the primary ligand (4MCFD) showed no clear change in the spectra of the complexes, indicating that the (N1) nitrogen of the of the imidazole ring does not participate in coordination. In contrast, the v(C-N) of the imidazole ring at 1253 cm -1 exhibited a clear shift in the complexes, supporting coordination through the (N3) nitrogen of the imidazole ring (Ward et al. 2022). These values exhibited noticeable changes in the complex's spectra because of the formation of coordination bonds with metal ions through the nitrogen atom of the imidazole ring (Abdullah et al. 2020). ...
