摘　　要：合成了4个新型的含羧基酰腙类配体H2L1-H2L4,通过元素分析、TG-DTA、IR、摩尔电导等方法表征了它们与Pb(Ⅱ)配合物的结构,结果表明,配体以四齿形式与Pb(Ⅱ)形成了1:1的配合物,其中羧基以桥式方式参与配位.Four new ligands of acylhydrazone containing carboxyl, H2L1-H2L4 were synthesized and their lead(Ⅱ) complexes have been characterized by elemental analyses, TG-DTA, IR, and molar conductivity. The result indicates that a 1:1 (metal: ligand) stoichiometry for the isolated complexes. The ligands behaved as tetradentate and the carboxyl in the ligands coordinated by way of bridging form.
