摘　　要：在四氢呋喃中合成了Ｓｃｈｉｆｆ碱配体Ｎ，Ｎ＇－二（２－羟基苄烯）－２－羟基苯甲基二胺（ＳＢ）与二价过渡金属镍、铜、锌的三核或双核配合物；用钠汞齐还原ＳＢ得到了其氢化物Ｎ，Ｎ＇－二（２－羟基苄基）－２－羟基苯甲基二胺（ＨＳＢ），并在乙醇中合成了它与铜的双核配合物。对这些配合物进行了元素分析和热分析，并测定了电导、红外光谱和紫外光谱，确定了分子式，讨论了可能的配位结构。Binuclear and trinuclear complexes of a Schiff base ligand,N,N'-bis(2-hydroxy-benzylidene)-2-hydroxyphenylmethanediamine(SB),with divalent transition metals Ni,Cu and Zn,have been synthesized in THF.Also,the hydrogenated product of the Schiff base ligand(HSB)and its copper complex liave been prepared in ethanol.These complexes were characterized by elemental analysis,thermogravimetric analysis,molar conductance,and UV and IR spectra.Cu3(SB)2·1.5THF is a trinulear complex with tetrahedral Cu1,Cu2 and square-pyramidal Cu3 coordination configurations.Ni2(SB)Ac2·THF and Zn2(SB)(Ac)2·THF are binuclear complexes,each metal ion is coordinated in a square-pyramidal configuration by 1N,1O of SB,two carboxylate oxygen of acetate and oxygen of THF.Binuclear Cu2(HSB)(Ac)2 is similar to Zn(Ni)-SB complexes,but metal ions are coordinated in a square-planar configuration.The metal ions in these polynuclear complexes are bridged by ligand SB or HSB.
