摘要：

Two three-dimensional lanthanide(Ⅲ) coordination polymers with the formula [Ln(PYDC)(NA)(H2O)]n [Ln=Gd(1), Eu(2), H2PYDC=pyridine-2,5-bicarboxylic acid, HNA=nicotinic acid] have been hydrothermally synthe- sized and characterized by elemental analysis, IR, and single crystal X-ray diffraction. The NA came from in situ decarboxylation of the part of PYDC. X-ray single crystal structural analyses reveal that complexes 1 and 2 are iso- morphous, they possess the 43·63 topology assembled by Gd3+/Eu3+ and two different multidentate carboxylate ligands. Magnetic measurements show that antiferromagnetic coupling exists between adjacent Gd3+ ions in complex 1. The complex 2 exhibits the corresponding characteristic luminescence in the visible region under an excitation at 305 nm.
