An O-Vanillin-methionine Schiff Base complex with copper(Ⅱ) has been synthesized under a mild condition. The complex has been characterized by elemental analysis, UV, FT-IR, TG-DTA and XRD. The crystal structure of the complex belongs to monoclinic, with space group C2/C, a=2.070 4(12) nm, b=1.431 9(8) nm, c=2.812 9(11) nm, β=133.15(2)°, V=6.084(5) nm 3, Z=8, D c= 0.998 Mg/m 3, F(000)=1 836, final R=0.121 8. The results revealed it is a tetranuclear copper(Ⅱ) complex.

The crystal structure of the complex belongs b = 1.431 9 (8) nm, c = 2.812 9 (11) nm, β = 133.15 (2) °, V = 6.084 (5) to monoclinic with space group C2 / ) nm 3, Z = 8, D c = 0.998 Mg / m 3, F (000) = 1 836, final R = 0.121 8. The results show that it is a tetranuclear copper (II) complex.
