Abstract: The complex [Cu(L)(H2O)]2·H2O (L=3-methoxysalicylideneimino benzoate)was synthesized.The complex crystallizes in an orthorhombic system.space group is Pcan,cell parameters: a=1.0347(4) nm,b=1.5493(7) nm, c=1.7441(3) nm,Z=4,with R=0.047,Rw=0.049.The kinetic parameters were obtained from the analysis of the TG-DTG curves by integral and differential method.The possible reaction mechanism is suggested by comparison of the kinetic parameters.The kinetic eqution may be exprested as dα/dt=A·e-E/RT·3(1-α)2/3 The mathematical expression of the kinetic compensation effect of the thermal decomposition reaction has also been obtained.
