摘　　要：合成了不对称双Schiff碱Cu(Ⅱ)单核配合物CuHL(H3L为N3羧基水杨醛N′水杨醛缩乙二胺)及其Cu(Ⅱ)Zn(Ⅱ)Cu(Ⅱ)异三核配合物。用元素分析、红外光谱、电子光谱对它们进行了表征,用X射线单晶衍射法测定了三核配合物的晶体结构。该三核配合物属三斜晶系,P1空间群,晶胞参数为a=11862(2)nm,b=15440(3)nm,c=19488(4)nm;α=9004(3)°,β=9786(3)°,γ=9012(3)°;V=35356(12)nm3,Z=1;R1=00614,wR2=01319。A Cu(Ⅱ) mononuclear complex CuHL of asymmetrical double Schiff base(Where H 3 L 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) nm 3 , Z =1; R 1 =0 061 4, w R 2 =0 131 9。
