Two novel lanthanide coordination polymers, {[Ln(stp)(bipy)(H2O)](H2O)}(n) [Ln = Eu (1) and Dy (2)], were synthesized by hydrothermal reactions of 2-sulfoterephthalate (stp) and 4,4-bipyridine (bipy) ligands with europium/dysprosium(III) salts. Structural analyses show that both complexes 1 and 2 are isomorphic and crystallize in the monoclinic crystal system with space group P2(1)/n. Complex 1 exhibits a two-dimensional grid-like structure from europium(III) ions bridged by the carboxyl and sulfonate groups of stp ligands. Notably, the stretching 4,4-bipyridine ligands besides the 2D grid-like layers form interactions and interpenetrate into the empty voids of another adjacent layer into a twofold interpenetrated structure. Fluorescence analysis show that the emission of two complexes exhibit the characteristic peaks of lanthanide ions.
