摘　　要：水热法合成了一个新颖稀土镨和对氯苯氧乙酸(PCPA)的配合物[Pr (PCPA)3(H2O)]n。对氯苯氧乙酸中的羧基以2种不同的配位方式与镨配位,最终形成了一维链状结构。对配合物的热重分析表明此配合物具有很好的稳定性,量化计算的结果与配合物的配位情况一致。A novel rare earth praseodymium and PCPA complex[Pr(PCPA)3(H2O)]n was synthesized by hydrothermal method.The carboxyl group in p-chlorophenoxyacetic acid coordinates with praseodymium in two different ways,and finally forms a one-dimensional chain structure.Thermogravimetric analysis of the complex was carried out,and the results show that the complex has good stability,and the result of quantitative calculation is in consistent with the coordination of the complex.
