摘　　要：三聚硫氰酸与3-氯丙酸反应得到1个具有3个丙酸基的柔性羧酸配体2,2',2″-[1,3,5-三嗪-2,4,6-三(硫代)]三丙酸(H_(3)TTPA),利用该配体分别与硝酸铜和硝酸铁反应,通过一步沉淀法,得到2个配合物(Cu-TTPA和Fe-TTPA)。通过X射线光电子能谱(XPS)、红外光谱(FTIR)、热分析(TG)对配体和配合物进行了结构表征,测定了2个配合物在不同pH值缓冲溶液中的稳定性及电导率。为柔性三嗪含硫多羧酸配体合成配合物的进一步研究提供了基础。A flexible carboxylic acid ligand with three propionic acid groups,2,2',2"-[1,3,5-triazine-2,4,6-tris(thio)]tripropionic acid(H_(3)TTPA)was synthesized by reacting trimeric thiocyanate with 3-chloropropionic acid.Two complexes(Cu-TTPA and Fe-TTPA)were obtained through one-step precipitation method using H,TTPA with copper nitrate or iron nitrate,respectively.The structures of the ligand and the corresponding complexes were characterized by X-ray photoelectron spectroscopy(XPS),infrared spectroscopy(FTIR),and thermal analysis(TG).The stability and conductivity values of the two complexes in buffer solutions with different pH levels were measured.This provides an experimental basis for further research on complexes formed by the flexible triazine sulfur-containing polycarboxylate ligands.
