Some of metal complexes were prepared by modified and simple reactions between Tryptophan (as ligand) with some metal ions of: Zn (II), Fe (III) and Cu (II). The complexes were investigated using several physical techniques as: molar conductance measurements, colour and melting point in addition to the infrared investigation spectra. The thermogravimetric analysis TGA was performed for the Complexes. The biological activity on effect of three complexes on egg hatching and mortality in RKN second-stage juveniles were studied.
