Three novel lanthanide coordination polymers {[Ce 2 (HOnic) 4 (Onic) 2 (H 2 O) 2 ]·6H 2 O} n ( 1 ), {[Ln(HOnic)(Onic)‐ (H 2 O) 5 ·(HOnicH)]·H 2 O} 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 1D 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 .
