| Abstract | ||
| A new complexes of some transition metal ions (Co(II),Ni(II),Cu(II)) and some non transition metal ions (Zn(II),Cd(II)) with a number of Schiff bases obtained from the condensation of some amino acids (Methionine) and (3-acetyl pyridine, 4-acetyl pyridine, acetoacetaanilide) have been prepared. All the prepared complexes have been characterized by elemental analysis, molar conductance, magnetic susceptibility infrared and electronic spectral. The complexes were classified as: A-mononuclear complexes: Complexes with the formulas [ML(CH3COO) ] (H2O) ,[ML (H2O) ] and [ML(CH3COO) (H2O)2]. B-Di nuclear complexes: Complexes with the formulas [M2(L)2(CH3COO)2] .2H2O and [M2(L) (CH3COO)3] H2O and [M2(L) (CH3COO)2(H2O)] M= Co(II),Ni(II),Cu(II),Zn(II)Cd(II). L= 3-acetylpyridine Methionineimine, 4-acetylpyridine Methionineimine and acetoacetanilide Methionineimine. The physical measurements showed that the prepared complexes may have a tetra coordinated (tetrahedral or square planer) and hexa-coordinated (octahedral) structure and that all the prepared complexes were non electrolyte. | ||
