A Cu(Ⅱ) mononuclear complex CuHL of asymmetrical double Schiff base(Where H₃L is N-3-carboxylsalicylidene-N'-salicylaldehyde diaminoethane) and a Cu(Ⅱ)-Zn(Ⅱ)-Cu(Ⅱ) trinuclear complex have been synthesized and characterized by elemental analysis, IR and UV-vis. The crystal and molecular structure of the trinuclear complex was determined by X-ray diffractometry. The work confirms that the trinuclear complex belongs to triclinic system and P1 space group. The cell parameters are a=1.186 2(2) nm, b=1.544 0(3) nm, c=1.948 8(4) nm; α=90.04(3)°, β=97.86(3)°, γ=90.12(3)°; V=3.535 6(12) nm³, Z=1; R₁=0.061 4, wR₂=0.131 9。
