“…The spectra of the metal chelates exhibited broad bands at 3448-3375 cm −1 that are attributed to OH of the crystal water molecules, while the bands observed at approximately 857-845 cm −1 are assigned to coordinated water molecules. 32,37 complexes. 38 All the vibrational data suggest that the metal ion bonded to the azo-azomethine ligand through the phenolic oxygen and the imino nitrogen atoms.…”

A new, substituted 2-[( E) -{[4-(benzyloxy)phenyl]imino} methyl]-4-[( E) -(4-nitrophenyl)diazenyl]phenol azoazomethine ligand (mbH) was synthesized from 2-hydroxy-5-[(4-nitrophenyl)diazenyl]benzaldehyde and 4-benzyloxyanilinehydrochloride in ethyl alcohol solution. These mononuclear Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) complexes ofthe ligand were prepared and their structures were proposed by elemental analysis, and infrared and ultraviolet-visible spectroscopy; the proton NMR spectrum of the mbH ligand was also recorded. The azo-azomethine ligand, mbH, behaves as a bidentate ligand coordinating through the nitrogen atom of the azomethine (-CH=N-) and the oxygen atom of the phenolic group. Elemental analyses indicated that the metal:ligand ratio was 1:2 in the metal chelates. Powder X-ray diffraction parameters suggested a monoclinic system for the mbH ligand and its Ni(II), Cu(II), Co(II), and Zn(II) complexes, and an orthorhombic system for the Mn(II) complex. Electrochemical properties of the ligand and its metal complexes were investigated in 1 × 10 −3 -1 × 10 −4 M DMF and CH 3 CN solvent in the range 200, 250, and 500 mV s −1 scan rates. The ligand showed both reversible and irreversible processes at these scan rates. In addition, genotoxic properties of the ligand and its complexes were examined.
