Synthesis and Spectral Study of new Tetradentate Azo-Azomethine ligand as a drevitave of 4,5-diphenyl Imidazole and it's Complexes with some of metal Ions
Abstract
A new azo ligand N1Z, N2Z) N1,N2-Bis ((E-4,5-Di phenyl-1H –imidazole-2-yl)diazenyl) 1,5-di methyl-2-phenyl -1H-pyrazole-3-(2H)-ylidene) ethan-1,2-diimine (BDIDE) prepared by coupling reaction between 4,5-diphenylimidazole and 1,2- Bis –(4’-Amino-2’,3’-Di methyl-1’-Phenyl- pyrazolinyl)-Diimino Ethan , The structure of ligand , mode of bonding, and overall geometry of it's complexes with Co(II),Ni(II) ,Cu(II), Zn(II), Cd(II), and Hg(II) were determined through IR,UV-Vis. , 1H-NMR , and Mass spectral studies , magnatic momentum , elemental analysis , and Molar conductance , also the stability constants of the complexes were calculated geometry for all complexes in which a ligand was a bidentate and coordinated with metal ions through N(3) imidazole and one of nitrogen atoms of azo group spectrophotometrically, These studies revealed octahedral
