The complex[Zn(L)(C~5H~5N)~2]·2H~2O(L=3-methoxysalicylidene-L-valine) was synthesized. The complex crystalizes in an orthorhombic system, space group is P2~12~12~1, cell parameters: a=0.9345(2), b=2.6620(5), c=0.9748(4)nm, V=2.425(2)nm^3, M~r=508.87, Z=4, with R=0.074, R~w=0.076. The kinetics of thermal decomposition reaction of the complex was studied under a non-isothermal condition by TG. The kinetic parameters were obtained from the analysis of TG, DTG curves by integral and differential methods. The kinetic equation of thermal decomposition reaction is: da/dt=A·e^-^E^/^R^T·(1-a).
