The solubility properties of ZnSO4-Leu-H2O system at 25℃ in the whole concentration range have been investigated by phase equilibrium method, and the corresponding phase diagrams and rafractive index-composition curve have been constructed. The result indicate that system is simple system, which do not exist any compound. Referred to literature, the compound of Zn(Leu)SO4•1/2H2O、 Zn(Leu)2 which are not reported in literature have been prepared. Their composition have been determined by chemical analysis and elemental analysis. Their propeties have been characterized by IR spectra, XRD and TG- DTG.

Key words: Ternary system, Zinc sulfate, L-Leucine, Complex
