| Abstract: | Four new lanthanide coordination polymers {Ln(HL)2(H2O)5] · HL · H2O}n (Ln = Sm for 1, Eu for 2, Tb for 3 and Dy for 4) (H2L = 6-hydroxynicotinic acid) have been synthesized and characterized by elemental analysis, FT-IR spectra and X-ray single-crystal diffraction. They all exhibit 1D chain structure, which are further linked via hydrogen bonds to form 3D supramolecular architecture. Luminescent properties of these lanthanide coordination polymers are studied. |
