Abstract EN

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.
