摘　　要：The crystal structure of the title compound [Cu (o-vanillin-ethylenediamine) (H2O)] is described. The complex crystallizes in the orthorhombic system, space group Pbn21 with formula = CuC18H20N2O5, cell dimensions are: a = 0.7490(3) nm, b = 0.9256(2) nm, c=2. 4691(6) nm, V=1.712 nm3, Z = 4, Dc=l.51 g/cm3. The kinetics of thermal decomposition of the complex was studied under the non-isothermal condition by TG. Kinetic parameters were obtained from the analysis of the TG, DTG curves by integral and differential methods. By comparison of the kinetic parameters, the most probable mechanism function is f(α) = (3/2) (1-α)[-ln(1-α)]1/3, and the mathematical expression for the kinetic compensation effect is lnA = 0. 201E+0. 531.The crystal structure of the title compound [Cu (o-vanillin-ethylenediamine) (H2O)] is described.
