The synthesis, crystal structure and thermoanalysis of 3-methoxysalicylaldehyde 1,2-diaminobenzene nickel (Ⅱ) complex, [ Ni(C8H7O2)2(C6H4N2)] · H2O, were reported in this paper. The complex lies in monoclinic, space group P21 / n with a = 0.8854(2), b= 1.9067 (5), c=1.1807(4)nm,β= 99.43(2)°, Z = 4, final R = 0.044, Rw = 0.052. Kinetic parameters were obtained from analysis of the TG, DTG curves by integral's method and differential's method. The possible reaction mechanism was suggested by comparision of the kinetic parameters. The kinetic equation may be expressed as:dα/dt = A · e-E/Rr·(3/2) ·(1-α)[-ln(1-α)]1/3The mathematical expression of the kinetic compensation effect of the thermal decomposition reaction had been obtained.
