Abstract

A series of isostructural lanthanide coordination polymers Ln-CPs, {[Ln2(PBA)3(H2O)3]·DMF·3H2O}n(Ln = La 1, Nd 2, Sm 3, Eu 4, Dy 5), based on a tripodal nitrogen-containing carboxylic ligand (H2PBA=5-(4-pyridin-3-yl-benzoylamino)-isophthalic acid), have been successfully synthesized under solvothermal conditions. Structural analyses show that compounds 1–5 are isomorphous and crystallize in triclinic space group Pī, and feature an interesting 3,3,6T13 network topology with point symbol (4·52)2(42.52.10·6·72)(58.64.10·6·72). There exist two kinds of 1D metal-carboxylate chains, which are further extended into 3D framework through the connection of PBA2- ligands. Moreover, luminescent spectra of compound 4 are also investigated in visible region, which indicates that it could be used to detect toxic metal cations with relatively high sensitivity and selectivity towards Hg2+ and Pb2+ in DMF solvent.
