Synthesis of o-vanillin (2-hydroxy-3-methoxybenzaldehyde) and anthranilic acid Schiff base copper (Ⅱ) complex, its crystal structure was determined and its thermal stability. The crystal C_ (30) H_ (28) Cu_2N_2O_ (11) belongs to the orthorhombic system with space group Pcan. The unit cell parameters are a = 1.0347 (4) nm and b = 1.5493 .7441 (3) nm, V = 2.7959 nm ~ 3, M = 719.64, Z = 4. The final concordance factor of structure analysis was R = 0.047, Rw = 0.049. The kinetic equation of thermal decomposition was: dα / dt = A · e ~ (-E / RT) · 3 (1-α) 2/3). The mathematical expression of compensation effect is: 1nA = 0.2858E + 0.4045.
