摘　　要：合成和表征了新的含硫席夫碱—安息香缩肼基二硫代甲酸甲酯 (H2 L)及与Mn(Ⅱ ) ,Co(Ⅱ ) ,Ni(Ⅱ )Zn(Ⅱ )和Cd(Ⅱ )生成的配合物 [M(HL) 2 ]。结果表明这些配合物中安息香缩肼基二硫代甲酸甲酯存在为去质子化的烯硫醇式三齿配体 ,通过甲亚胺基氮原子、醇羟基氧原子和烯硫醇硫原子配位 ,金属离子处于六配位的八面体环境。The new sulphur-containing Schiff base derived from benzoin and S -methyldithiocarbazate [H 2L] and its Mn(Ⅱ),Co(Ⅱ),Ni(Ⅱ),Zn(Ⅱ) and Cd(Ⅱ) complexes of formula [M(HL) 2], has been synthesized and characterized. The study reveals that the Schiff base behaves as a tridentate ligand in the deprotonated enethiolate form and coordinates via azomethine nitrogen, hydroxyl oxygen and enethiolate sulphur. The metal ions are in octahedral coordination environments.
