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 (2-acetylfuran) 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: A-mononuclear complexes.         1-Complexes with the formulas  [ML(CH3COO) (H2O)2].         2- Complexes with the formulas  [ML(CH3COO) ] H2O. B-Homo dinuclear complexes.           Complexes with the formulas [M2(L)2(CH3COO)2] .2H2O.                    M= Co(II),Ni(II),Cu(II),Zn(II)Cd(II). L= 2-Acetyl furan isoleucine imine, 2-Acetyl furan phenylalanine imine and        2-Acetyl furan 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.
