摘      要：Two new coordination complexes, [Pr（1,3-pda）0.5（nbca）2（H2O）2]（1） and [Pr2（1,3-pda）3（2,2ˊ-bpy）2（H2O）2]（2）（H2pda = 1,3-phenylenediacetic acid, Hnbca = 5-nitro [1,1ˊ-biphenyl]-3-carboxylic acid, 2,2ˊ-bpy = 2,2ˊ-bipyridine）, have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. In 1, the nbca ligands bridge the Pr3＋ ions to form a 1D chain. Moreover, these 1D chains are united together through the 1,3-pda ligands to afford a 2D layer. In contrast, due to a different auxiliary ligand, complex 2 is a 2D layer linked through only bridging deprotonated 1,3-pda. Thermal stabilities and solid fluorescence properties of 1 and 2 were also studied.
