摘　　要：以1-(3,5-二羧基苄基)-1,2,4-1H-三唑-3-羧酸(H_(3)L1)为有机配体,选择Cu^(2+)和Pb^(2+)为金属中心,通过溶剂热反应制备得到两种新的配合物[Cu(L1)·(CH_(3)CN)_(2)]·H_(2)O(1)和[Pb(L2)](2),H_(2)L_(2)为H_(3)L1原位脱羧产物,并通过单晶X-射线衍射、红外光谱、X-射线粉末衍射、热重分析等对配合物进行表征和分析.染料吸附实验结果表明,配合物1对亚甲基蓝的吸附效率为84.0%,而配合物2对结晶紫的吸附效率为60.2%.Two new complexes of[Cu(L1)·(CH_(3)CN)_(2)]·H_(2)O(1)and[Pb(L2)](2,H_(2)L_(2)derived from the in-situ decarboxylation of H_(3)L1)were prepared by solvothermal reaction using 1-(3,5-dicarboxybenzyl)-1,2,4-1H-triazol-3-carboxylic acid(H_(3)L1)as organic ligand,and Cu^(2+)and Pb^(2+)as metal centers.The crystal structures and other related properties were characterized by single crystal X-ray diffraction,Infrared spectroscopy,X-ray powder diffraction and thermogravimetric analysis.In addition,dye adsorption experiments show that complex 1 adsorbs methylene blue with 84.0%adsorption efficiency and complex 2 adsorbs crystal violet with 60.2%adsorption efficiency.
