摘要：

The solubility of ZnSO4 - Thr - H2O system at 25 degreesC in the entire concentration range has been investigated by phase equilibrium method. The corresponding phase diagram and refractive index diagram have been constructed. The results indicate that system is a simple one, which does not have any new compounds. The compound of Zn(Thr)SO4.H2O, which is not reported in the literature, has been prepared in acetone water mixture solvent. The compound is characterized by IR spectra, XRD, XPS and TG - DTG, as well as chemical and elemental analyses. The constant volume combustion energy of the complex, Delta E-c,E-coor, has been determined by a precision rotating bomb calorimeter at 298.15K. The standard enthalpy of combustion, Delta H-c,coor(theta), and standard enthalpy of formation, DeltaH(f,coor)H(theta), are calculated for the complex.
