Schiff bases derived from vanillin and amino acids (glycine, L-serine, L-tyrosine and L-phenylalanine) and their complexes with Fe(III)have been prepared and characterized by many physicochemical methods such as elemental analysis (CHN), magnetic susceptibility, molar conductance as well as spectral studies such as IR and UV-Visible. The analytical data showed that the complexes having four and six coordination number with the following formulas [Fe(VA)(H2O)2Cl]2,[Fe2(VA-)(CH3COO)(OH)2], where A-=serine or tyrosine [Fe2(Vg)(CH3COO)(OH)2][Fe2(VA*H2)2(H2O)2(NO3)2](NO3)4 and[Fe2(VA*)2(H2O)2(NO2)2], A* =all the amino acids .The ligands behave as tetradentatecoordinating through the atoms NOOO, or tridentate NOO; where V= vanillin, A= amino acids (glycine and phenylalanine).
