Novel one-dimensional coordination polymers and a hydrogen-bonded supramolecular complex generated from a new unsymmetric oxadiazole bridging ligand and Cu(II) salts

Two one-dimensional Cu(II) coordination polymers and one hydrogen-bonded supramolecular complex were synthesized based on a new unsymmetrical oxadiazole bridging ligand L7 (2-[(3-pyridyl)]-5-[(4-pyridyl)]-1,3,4-oxadiazole). In addition, the luminescent properties of L7 and its Cu(II) coordination polymers were investigated preliminarily in the solid state.
