A new complexes of some transition metal ions (Co(II),Ni(II),Cu(II)) and non transition metal ions (Zn(II),Cd(II)) with a number of Schiff bases obtained from the condensation of some amino acids isoleucine, phenylalanine and alanine with (3-acetyl Indol) have been prepared. All the prepared complexes have been characterized by elemental analysis(M), molar conductance, magnetic susceptibility infrared and electronic spectral. The complexes were classified as:
1-Complexes with the formulas [ML(CH3COO) (H2O)2].
2- Complexes with the formulas [ML(CH3COO) ] H2O.
M= Co(II),Ni(II),Cu(II),Zn(II)Cd(II).
L= 3-acetyl Indol isoleucine imine, 3-acetyl Indol phenylalanine imine and 3-acetyl Indol alanine imine.
The physical measurements showed that the prepared complexes have a tetra coordinated (tetrahedral) and hexa-coordinated (octahedral) structure and that all the prepared complexes were non electrolyte.
