Synthesis and Spectral identifications of new azo – Schiff base ligand(4Cl-2DIBP) derived from (para-aminobenzylamine) with its some metallic complexes
Keywords:Azo – Schiff base ligand, 4,5-diphenyl imidazole, para-aminobenzylamine
The New Heterocyclic ligand 4-chloro-2-(((4-((4,5-diphenyl-1H-imidazol-2-yl) diazenyl ) benzyl)imino)methyl) phenol (4Cl-2DIBP) was prepared from the condensation of para-aminobenzylamine with 4,5-diphenyl imidazole, followed by the condensation of the resulting compound with 5- chloro-2- hydroxy benzaldehyde. Different analytical and characterization techniques including (Mass,1HNMR, FT-IR and UV-Vis. spectroscopy and C.H.N elemental analysis) in the investigation of Newly prepared ligand. A series of Novel solid metal complexes of this ligand with Co (II), Ni (II), Cu (II), Zn ((II), Cd (II), and Hg (II) were prepared and all complexes were characterization by techniques above, excluding the Mass and the 1H-NMR spectroscopy of some prepared solid metal complexes and the use of flame atomic absorption spectroscopy to determine the percentages of metal ions in the prepared complexes also studied the magnetic susceptibility and molar conductivity of the metal complexes dissolved in DMSO at 1 × 10-3 M concentration laboratory temperature. The results of this studies showed that the coordination sites for the new Azo-Schiff base ligand with Co (II), Ni (II), Cu (II), Zn ((II) , Cd (II) and Hg(II) were to be through nitrogen of the imidazole ring, and the nitrogen of azo group,. The Electronic spectral and magnetic measurement data predict octahedral structure of the complexes. All complexes showed that Non-electrolytes properties.
