The complex of Zn Ac2•2H2O and Threonine was prepared in the mixed solvent of water - acetone, the composition of the complex was identified as Zn(Thr) Ac2•2H2O by chemical, elemental analyses. The structure and thermal stability of the title complex were investigated by IR, XRD and TG - DTG. Enthalpy of solution of the complex was determined at 298.15 K in water by microcalorimetry.Standard molar enthalpy of formation of Zn(Thr)2＋(aq,∞) and that of Zn(Thr) Ac2•2H2O (s)were calculated to be (955.24 ± 5.70) kJ•mol-1 and (-570.92±5.71) kJ•mol-1,respectively.
