摘要：Three stable coordination polymers(CPs)assembled by 3,5-(carboxybenzyloxy)-benzoic acid(H3L)and 1,10-phenanthroline(phen),namely,[Zn(HL)(phen)]n(1),[Cd(HL)(phen)]n(2)and[Co(HL)(phen)]n(3),have been synthesized under hydrothermal conditions.Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses,infrared(IR)spectroscopy and powder X-ray diffraction(PXRD).Investigation on crystal structure indicates that complexes 1-3 exhibit similar architecture.In these complexes,metal ions coordinate with H3L and phen ligands,forming infinite ID chains.Then the adjacent chains combine together through intramolecular hydrogen-bonding interactions,generating 2D supramolecular architectures.In addition,complexes 1~3 present excellent thermal stabilities and 1 and 2 exhibit strong luminescent emission bands at room temperature.
