This work deals with the preparation, characterization and kinetic studies on base hydrolysis of some Fe(II) Schiff base amino acid complexes.The prepared complexes were found to be of 1:2 or 1:1 stoichiometry and non - electrolytic character, solubility measurements of these complexes showed them as hydrophobic in nature. The base hydrolysis reaction of the prepared complexes was carried out in aqueous, co-organic media and in the presence of added salts. The kinetic measurements confirmed the pseudo 1st - order rate dependence in [complex] and 2nd - order in [OH-]. A relevant mechanism was suggested in which the parallel attack of OH- ion on the central Fe(II) atom and the dissociation of the first ligand is provided as rate - determining step. The observed decrease of base hydrolysis rate constant kobs. with increasing the mole fraction of co-organic solvent indicates solute - solvent interaction between delocalized charge in complex and dispersion centers on solvent molecules.
