Synthesis and Characterization of Some Transition Metal Complexes with New Azo- Schiff Base Ligand 3,4-bis(((1E,2E)-2-((2-((4-((Z)-(3-Hydroxyphenyl)Diazenyl)Naphthalen-1-yl)amino)ethyl)imino)-1,2-Diphenylethylidene)Amino)Phenyl)(phenyl)Methanone

Abstract

A NEW Azo-Schiff base derivative (3,4-bis(((1E,2E)-2-((2-((4-((Z)-(3-hydroxyphenyl) diazenyl)naphthalen-1-yl)amino)ethyl)imino)-1,2-diphenylethylidene)amino)phenyl) (phenyl)methanone (HANPH) and its metal complexes which include Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Pt(II), and Au(III) metal ions were synthesized. The structure of these compounds has been investigated by using elemental analysis, FT-IR, UV-Vis spectrometric methods, 1 H-NMR, mass spectra, atomic absorption, molar conductivity and magnetic susceptibility of metal complexes. The spectroscopic data of the complexes suggest that their (1:1) (metal: ligand) is mole ratio. Also, the analytical studies for all new complexes have shown octahedral geometries, except for Pt (II) and Au (III) complexes which suggested square planar geometries also its conductivity measurements show electrical properties. These complexes show high conductance value supporting (1:1) electrolytic nature. Furthermore, the FTIR results show that the coordination site from the ligand to the metal ions were through the nitrogen of azomethine group and the nitrogen of the azo group for all new complexes, except for Pt (II) and Au (III) complexes which were through the nitrogen of imine groups only.

Exploring the Anticancer Activity of Gold Complex with Newly Ligand (DDIBM): Synthesis, Spectral Identification and Magnetic Susceptibility of Its Metallic Complexes

“…The -NH-group in the imidazole ring is slightly shifted to 3377-3132 cm −1 in complexes. While the C=N of the imidazole is changed in its intensity and that suggests the coordination with the metals by this group as this stimulated from the previously published articles [17,25,31]. The azo-imine group which appears at 1631 cm −1 in the free ligand was shifted to 1629, 1624, 1627, and 1595 cm −1 in Co(II), Ni(II), Cu(II), and Au(II) complexes, respectively, which suggests the coordination between the metal and the ligand azo-imine group.…”

“…The reaction was carefully monitored by applying TLC technique using 1 mL benzene and 4 mL ethanol. The product obtained was cooled, dried, and recrystallized through hot absolute ethanol [31]. The physical properties are listed in Table 1.…”

“…In addition to the disappearing of asymmetric stretching vibrational mode of NH2 group because of diazotization coupling reaction through this group with 2-hydroxyquinolin. Other absorption bands were clearly observed at 3381 cm -1 , 3091 cm -1 , 2977 cm -1 and (1160 -1086) cm -1 for each of the following groups : (NH) amine, (C-H) aromatic, (C-H) aliphatic and (SO2) respectively 25 .
