【摘要】 用邻甲酰基苯氧基乙酸与二氨基硫脲和水合肼为原料，经缩合反应，合成了３个新型的希夫碱化合物，通过元素分析，ＴＧＡ，ＩＲ和１ＨＮＭＲ等方法表征了它们与铅（Ⅱ）配合物的结构．结果表明，配体分别以双碱基四齿和双碱基二齿形式与铅（Ⅱ）形成了１：１的配合物更多还原

【Abstract】 Three new Schiff base ligands have been prepared by condensation of (o formylphenoxy) acetic acid with thiocarbohydrazide and hydrazine. These ligands and their lead (II) complexes have been characterized by their elemental analyses, TGA, IR, UV and 1HNMR Spectra. The data suggest a 1:1 (metal : ligand) stoichiometry for the isolated complexes. The ligands behave as dibasic quadridentate and dibasic bidentate, respectively.更多还原
