Anewseries of transformation metal complexes of Mn(II), Co(II), Ni(II), Cu(II), Zn(II),and Cd(II), with Schiff base (L) bisimine (4,4'-(3,3'-dimethylbiphenyl-4,4'-diyl) bis (azan-1-yl-1-ylidene) bis(methan-1-yl-1-ylidene) bis (2-methoxyphenol)) ligand, type (O4) was prepared by condensation of (vaniline) ( 4-hydroxy 3- methoxybenzaldehyde) with o- Tolidine, by (2:2) metal to ligand molar ratio. The complexes were characterized by metalanalysis, magnetic susceptibility, molar conductance and IR, UV-Vis,1H NMR spectral studies.
From the spectroscopic studies, magnetic moments, mole ratio and physical properties the suggested geometry for the prepared complexes, we suggest the octahedral Cobalt(II) and Copper(II) Complexes with ligand andthe tetrahedral geometry suggested for Manganese(II), Nickel(II), Zinc(II), Cadmium(II)complexes.The results submit that the metal is connective with the ligand during the methoxy and phenolic group.
