摘　　要：合成并表征了异双核配合物 Cu Zn TS·CH3OH[TS为二 (3 -羧基水杨醛 )缩 -1 ,3 -丙二胺 ]。晶体结构分析表明此配合物属三斜晶系 ,空间群为 P1 ,晶格参数为 a=0 .9440 3 (1 9) nm,b=1 .1 5 91 (2 ) nm,c=0 .91 3 2 2 (1 8) nm ,α=91 .0 9(3 )°,β=97.0 6(3 )°,γ=75 .0 6(3 )°,Z=2。最终一致性因子 R1 =0 .0 499,w R2 =0 .1 3 1 8。异双核 Cu Zn TS· CH3OH配合物中的 2个金属原子通过酚氧原子桥联在一起 ;铜原子与 2个氮原子、2个酚氧原子和 1个甲醇分子配位形成变形的四方锥结构 ;锌原子与 2个酚氧和 2个端基羧氧配位 ,并与相邻分子中的 1个端基羧氧原子存在弱的配位相互作用 ,锌原子也处于变形四方锥几何构型之中。结合晶体结构对配合物做了电化学性质研究。The complex CuZnTS·CH_3OH, where TS denotes the binuclear ligand derived from the Schiff base N,N-bis(3-carboxylsalicyl aldehyde)trimethylenediamine, was synthesized and its crystal structure was determined by the single-crystal X-ray diffraction method at room temperature. The complex crystallizes in triclinic system with space group P1. The lattice parameters are a=0.944 03(19) nm, b=1.159 1(2) nm, c=0.913 22(18) nm, and α=91.09(3)°, β=97.06(3)°, γ=75.06(3)°, Z=2 with R1=0.049 9, wR2=0.031 8. The structure is consisted of heterobinuclear units, where the copper atom is fivefold coordinated by two nitrogens, two phenolic oxygens, and one oxygen of a methanol molecule in a distorted square pyramid, and the zinc atom is also in a distorted square pyramid manner, coordinated by two phenolic oxygen atoms, two equatorial carboxyl oxygen atoms and one oxygen of the adjacent molecular. The cyclic voltametric behavior of the complex is briefly examined.
