A novel 1-D coordination polymer constructed from disilver-1,3,4-oxadiazole nodes and perchlorato bridges

The reaction of silver perchlorate with 2-phenyl-5-( p -tolyl)-1,3,4-oxadiazole ( L ) affords a 1-D coordination polymer, [Ag 3 L 4 (ClO 4 ) 3 ] ( 1 ). Two silver ions are bridged by two L ligands, through the nitrogen atoms of the oxadiazole ring, resulting in binuclear units. The coordination polymer is constructed from binuclear nodes, {Ag 2 L 2 }, connected by perchlorato bridges. The investigation of the optical properties of compound 1 indicates a slight change in the emission profile compared to the organic ligand, showing blue luminescence upon excitation at λ = 300 nm.
