Two novel coordination polymers, [Ag(L 1 )(NO 3 )] n 1 and [Ag(L 2 ) 2 (ClO 4 )] n 2 [L 1 = 1‐(1‐benzotriazole‐yl‐)triazole, L 2 = 1‐(4‐chloro‐pyridazine‐yl‐)triazole] have been synthesized and characterized. Single‐crystal X‐ray analyses show that the Ag(I) atom is in a four‐coordinated distorted tetrahedron environment, which are linked by the coordinated nitrate group and L 1 into a two‐dimensional network in complex 1 . While in the complex 2 , the Ag(I) is also in a distorted tetrahedron environment consisting of four N atoms to present a one‐dimensional infinite chain, the intermolecular π− π stacking action extends further the repeated units into three‐dimensional topological framework. The biological activities of the title compounds have been studied. The results indicate that two ligands exhibit excellent radical‐scavenging activities and certain fungicidal activities, and both Ag(I) complexes only have good antibacterial activities. Furthermore, the studies on luminescent properties of the complexes in the solid state indicate that the Ag(I) complexes exhibit weaker fluoresce intensity than that of ligands at room temperature.
