摘要：

Two novel 1D and 3D Sm(III) coordination polymers involving the 2-pyridin-4-yl-4,5-imidazoledicarboxylic acid (H3PIDC) ligand have been characterized by infrared spectroscopy, elemental analysis and single-crystal X-ray diffraction. The coordination polymers were synthesized under hydrothermal conditions. Coordination polymer 1 gave a 1D zigzag chain, then forming 3D supramolecular structure through pi a <-pi stacking interactions and hydrogen bonds. Coordination polymer 2, in which oxalate was introduced as the second ligand gave a 3D framework with a 3,3-connected (4.8(5))(4.8(2)) topology structure. But the luminescence of the coordination polymers has significant quenching.
