| 摘 要： | 以1,1′-二羟基-5,5′-联四唑(H_2BTO)为配体,镧系金属离子作为金属中心,采用溶剂热法制备了5种金属配合物:La_2(BTO)_3(H_2O)_8]·2H_2O (1)、Ce_2(BTO)_3(H_2O)_8]·2H_2O (2)、Pr_2(BTO)_3(H_2O)_8]·2H_2O (3)、Sm_2(BTO)_3(H_2O)_8]·2H_2O (4)和Nd_2(BTO)_3(DMF)_4]·6H_2O (5)。通过单晶X射线衍射和元素分析对5种配合物的结构进行了表征。结果表明,5种配合物均属于单斜晶系,P2_1/n空间群。利用差示扫描量热法研究了配合物1～4的热稳定性,采用Kissinger法和Ozawa法分别计算了其热分解动力学参数。

| Abstract: | Five lanthanide metal complexes,La2(BTO)3(H2O)8]·2H2O (1),Ce2(BTO)3(H2O)8]·2H2O (2),Pr2(BTO)3(H2O)8]·2H2O (3),Sm2(BTO)3(H2O)8]·2H2O (4) andNd2(BTO)3(DMF)4]·6H2O (5), were synthesized by solvothermal method with 1H,1''H-5,5''-bitetrazole-1,1''-diolate (H2BTO) as ligand and lanthanide metal ions as metal centers. The structures of five complexes were characterized by single crystal X-ray diffraction and elemental analysis. The results show that all the complexes belong to monoclinic system, P21/n space group. The thermal stability of complexes 1~4 was investigated by differential scanning calorimetry. And their kinetic parameters of thermal decomposition were calculated by Kissinger method and Ozawa method, respectively. |
