The crystal of o-vanillin L-methionine dipyridine Zinc(Ⅱ)-ZnVAL C~2~8H~3~0N~4O~4SZn was synthesized and its structure was determined by single crystal X-ray diffraction method. The complex is orthorhombic system, space group P2~12~12~1 with a=0.9259(2), b=1.4409(4), c=2.1046(8)nm, Z=4, final Rw=0.080 for 1378 unique reflections Ⅰ≥3σ(Ⅰ). 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 was obtained too.
