| Abstract | ||
| The synthesis of some new complexes was performed by the reaction of Co(II), Ni(II), Cu(II) and Zn(II) metal ions with Schiff base (molar ratio 1:1). The ligand bis (α- acetonyl benzylidine) - 4,4- - diaminodi phenyl methane (AB)2 – APM was obtained by the condensation of 4, 4- diaminodiphenyl methane with benzoyl acetone .The complexes of the general formula [M2LH2Cl4] and [M2LCl2] (where LH2 and L are neutral and dibasic form of the ligand , M=Co(II), Ni(II), Cu(II) or Zn(II). For those formed by the reaction of metal salts and the ligand in neutral and basic medium, respectively. The resulting complexes were characterized by using elemental analysis, molar conductances , infrared , electronic spectra and magnetic measurements. These studies revealed that {(AB)2 – APM} ligand formed tetradentate dinuclear and high stability complexes with most expected tetrahedral or square planar for complexes formed in neutral and alkaline medium. | ||
