A new Ag(I) coordination polymer [AgL(NO3)]n 1 (L = 4-(pyridine-2-yl)methyleneamino-1,2,4-trizaole) has been synthesized and characterized by IR spectroscopy, elemental analysis, powder and single-crystal X-ray diffraction. The Ag(I) atom has a seesaw environment with an N3O donor set from three N atoms of two ligands and one O atom of one NO3− anion. Each twisted tridentate ligand is bound to two silver centers, and each silver atom is coordinated by two ligands thereby generating a zigzag chain structure. The chains interact with each other featuring a three-dimensional supramolecular network through multiple weak C–H··· π interactions and C–H···O hydrogen bonds. The luminescence properties
of the polymer 1 were investigated in the solid state at room temperature.
