A new series of lanthanide coordination polymers, namely, [Ln(ad) 0.5 (2,5-pydc)(H 2 O)] (Ln = Eu ( 1 ), Pr ( 2 ), Nd ( 3 ), Sm ( 4 ), Tb( 5 ); H 2 ad = adipic acid; 2,5-H 2 pydc = 2,5-pyridine dicarboxylic acid), have been synthesized hydrothermally from the self-assembly of the lanthanide ions (Ln 3+ ) with the flexible adipic dicarboxylate ligand and the rigid 2,5-pyridine dicarboxylic acid ligand. All of them were characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. Structural analyses reveal that all five complexes have intricate three-dimensional net-structures, and in these complexes, they were crystallized in monoclinic space group P 2 1 / c . In addition, the phase purities of the bulk samples were identified by X-ray powder diffraction. The thermogravimetric analysis of 1 and photoluminescent properties of 1 and 5 are discussed in detail.
