Abstract	Five new lanthanide coordination polymers, [Ln2(1,4-NDC)2(1,4-HNDC)2(phen)2]n (Ln = Er (1), Yb (2)), and [Ln2(1,4-NDC)3(phen)2(H2O)2]n (Ln = Nd (3), Gd (4), Er (5)) (1,4-H2NDC = 1,4-naphthalenedicarboxylic acid, phen = 1,10-phenanthroline), have been successfully prepared via the reaction of corresponding trivalent lanthanide salt, 1,4-H2NDC and phen in the presence of NaOH and pyridine under hydrothermal condition. Pyridine plays a key role in the synthesis of these lanthanide coordination polymers. Single-crystal X-ray diffraction analyses indicate that compounds 1-5 all form a 2-D network while different salt anions result in the diversity of crystal structures. These lanthanide coordination polymers showed a considerable thermal stability in TGA analyses.
