Three stable coordination polymers(CPs) assembled by 3,5-(carboxybenzyloxy)-benzoic acid(H3 L) and 1,10-phenanthroline(phen), namely, [Zn(HL)(phen)]n(1), [Cd(HL)(phen)]_n(2) and [Co(HL)(phen)]_n(3), have been synthesi...Three stable coordination polymers(CPs) assembled by 3,5-(carboxybenzyloxy)-benzoic acid(H3 L) 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 H3 L and phen ligands, forming infinite 1 D chains. Then the adjacent chains combine together through intramolecular hydrogen-bonding interactions, generating 2 D supramolecular architectures. In addition, complexes 1～3 present excellent thermal stabilities and 1 and 2 exhibit strong luminescent emission bands at room temperature.展开更多
