摘要Two new coordination complexes, [Pr(1,3-pda)0.5(nbca)2(H2O)2] (1) and [Pr2(1,3- pda)3(2,2'-bpy)2(H2O)2] (2) (H2pda = 1,3-phenylenediacetic acid, Hnbca = 5-nitro [1,1'-biphenyl]- 3-carboxylic acid, 2,2'-bpy = 2,2'-bipyridine), have been synthesized under hydrothermal con- ditions 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.
