摘　　要：以邻羧基苯乙酸(H2Hpa)和硝酸镧为原料在水热条件下合成了一种新的镧配合物1[La2(Hpa)3(H2O)2]n。单晶结构分析表明,配合物1是一个以双链[La2(Hpa)3]n为次级结构单元的二维结构,属单斜晶系,P21/c空间群。拓扑结构表明,配合物1是一个4, 6-连接的双节网络结构,拓扑符号为{411·64}2{44·62}{46}2。A novel lanthanum coordination polymer, namely, [La2(Hpa)3(H2O)2]n(1)(H2Hpa = o-carboxyphenylacetic acid) were synthesized under hydrothermal conditions. X-Ray single crystal diffraction analysis reveals that the complex crystallize in monoclinic, space group P21/c. The complex features is a two-dimensional structure based on double strands [La2(Hpa)3]n secondary building units. The 2 D structure of 1 can be described as a two nodal(4,6)-connected {411.64}2{44.62}{46}2 topological structure.
