摘要：

hree novel lanthanide coordination polymers {[Ce-2(HOnic)(4)(Onic)(2)(H2O)(2)]center dot 6H(2)O}(n) (1), {[Ln(HOnic)(Onic)-(H2O)(5)center dot(HOnicH)]center dot H2O}(n) [[HOnicH=6-hydroxynicotinic acid, Ln=Nd (2), Pr (3)] have been synthesized and characterized by elemental analyses, IR spectrum and single crystal X-ray diffraction. Structure analyses reveal that 1 features a 2D plane structure while compounds 2 and 3 possess a ID chain-like polymeric structure. TG analyses indicate that 1 exhibits higher thermostability than 2 and 3, which was attributed to the layer polymeric structure of 1.
