| Abstract: | Five two-dimensional lanthanide coordination polymers: Ln2(TDA)3(bipy)2(H2O)2]·bipy·2H2O (Ln = Nd (1), Sm (2), Eu (3), Tb (4), Yb (5), TDA = thiophene-2,5-dicarboxylic acid anion, bipy = 2,2′-bipyridine) were fabricated and structurally characterized. Compounds 1–5 are isostructural belonging to the triclinic system with space group P-1. Luminescence analyses were performed on coordination polymers containing Eu3 + and Tb3 +, and compound 3 shows a warm white light emission upon excitation. |
