Abstract
Abstract In this paper the synthesis and characterization of some binuclear complexes of cobalt (II), nickel(Il) and cupper(fl) ions have been reported. These complexes have been prepared by the reaction of metal nitate or chloride of the above transition metals with Schiff base ligand derived from benzil and malonyl hydrazide the prepared complexes have the general formula: [M2(BDM[L)]LI and [Mr(BDM)] for neutral and basic mediums respectively. Where M:Co(II), Ni(ll) and Cu(ll) ions, BDMHa:hydrazide ligand, and X: NO3- or Cl' ions. The ligand and its complexes were characterized by elemenlal analysis, molar conductance, magnetic susceptibility measurements, electronic and infiared spectroscopy. The ligand acts as an octadentate to form neutral complexes with the melal ions under investigation the measurements showed that some of these prepared complexes have an octahedral geometry (neutral medium) and the prepared complexes were in tetrahedral or squar planner environment(basic medium). Powder x-ray diffraction technique was applied for two ofthe prepared complexes, whereas crystal structural information's were obtained crystal symmetry, space group, unit cell, axis, unit cell volume...etc.
