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 ? 2H_2O} (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 ID chain via the hydrogen bond interactions. Furthermore, the luminescent properties of I--III show the strong emissive power and feature.
