Syntheses, luminescence, and hirshfeld surface analyses of three lanthanide coordination polymers directed by flexible carboxylate ligand

摘要

Three new complexes, namely {[Ln(L)3(2,2'-Bipy)] (n) center dot 2H(2)O} (Ln = Pr (I), Sm (II) and Nd (III)) (HL = 3-(4-hydroxyphenyl)propanoic acid), have been synthesized and structurally characterized by single-crystal X-ray diffraction analyses (CIF files CCDC nos. 1045041 (I), 1045042 (II), 1045043 (III)). The structural determination revealed that I-III have similar dinuclear motifs, which can be further linked into 1D chain via the hydrogen bond interactions. Furthermore, the luminescent properties of I-III show the strong emissive power and feature.
