摘要：

Four novel lanthanide-based coordination polymers, [Ln(PBDC)(HPBDC)(H2O)(3)] (H2PBDC=p-carboxylphenoxyacetate; Ln = La (1), Pr (2), Nd (3)) and [La-2(PBDC)(3)(H2O)(4)] (4), have been prepared through hydrothermal synthetic methods. Compounds 1-3 are isomorphous and exhibit one-dimensional (1 D) chain-like motifs, while compound 4 features a complicated three-dimensional (3D) architecture, which is designed and synthesized based on the inspiration from the structure characterization of compound 1. Under the similar reaction conditions, the carboxyl in compound 1 may be further deprotonated by adding the organic base of 2,2'-bipyridine. This subtle change caused a significant difference in the structures, from 1 D chain of 1 to a 3D structure of 4. In addition, IR, UV-Vis, TGA and magenetic properties are also investigated in this paper.
