摘要：

Reactions of H(3)tda (H(3)tda = 1H-1,2,3-triazole-4,5-dicarboxylic acid) with Sm(NO3)(3)center dot 6H(2)O, Eu(NO3)(3)center dot 6H(2)O, and Tb(NO3)(3)center dot 6H2O, in the presence of NaOH under hydrothermal conditions, produced three new coordination polymers, [Ln(2)(tda)(2)(H2O)(3)]center dot 5H(2)O [Ln = Sm (1), Eu (2), Tb (3)]. These compounds were structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA), PXRD and single-crystal X-ray diffraction. The single-crystal X-ray diffraction studies of compounds 13 reveal that all compounds are three-dimensional porous structures with chiral frameworks. Furthermore, the luminescence studies of compound 2 and 3 in the solid state reveal that they are potential luminescent materials at room temperature.
