3D Coordination Polymers with Chiral Structures, [Ln2(tda)2(H2O)3]·5H2O: Hydrothermal Synthesis, Structural Characterization, and Luminescent Properties

Reactions of H3tda (H3tda = 1H‐1, 2, 3‐triazole‐4, 5‐dicarboxylic acid) with Sm(NO3)3·6H2O, Eu(NO3)3·6H2O, and Tb(NO3)3·6H2O, in the presence of NaOH under hydrothermal conditions, produced three new coordination polymers, [Ln2(tda)2(H2O)3]·5H2O [Ln = Sm (1), Eu (2), Tb (3)]. These compounds were st...

Description
Summary:Reactions of H3tda (H3tda = 1H‐1, 2, 3‐triazole‐4, 5‐dicarboxylic acid) with Sm(NO3)3·6H2O, Eu(NO3)3·6H2O, and Tb(NO3)3·6H2O, in the presence of NaOH under hydrothermal conditions, produced three new coordination polymers, [Ln2(tda)2(H2O)3]·5H2O [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 1–3 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.
