The title compound, [Ag(C 15 H 11 N 4 O 2 S)] n , was synthesized by the reaction of 4‐{[(1‐phenyl‐1 H ‐tetrazol‐5‐yl)sulfanyl]methyl}benzoic acid (Hptmba) with silver nitrate and triethylamine at room temperature. The asymmetric unit contains one crystallographically independent Ag I cation and one ptmba − ligand. Each Ag I cation is tricoordinated by two carboxylate O atoms and one tetrazole N atom from three different ptmba − ligands, displaying a distorted T‐shaped geometry. Three Ag I cations are linked by tris‐monodentate bridging ptmba − ligands to form a one‐dimensional double chain along the c axis, which is further consolidated by an intrachain π–π contact with an offset face‐to‐face distance of 4.176 (3) Å between the centroids of two adjacent aromatic rings in neighbouring benzoate groups. The one‐dimensional chains are linked into a three‐dimensional supramolecular framework by additional π–π interchain interactions, viz. of 3.753 (3) Å between two phenyl substituents of the tetrazole rings and of 4.326 (2) Å between a benzoate ring and a tetrazole ring. Thermogravimetric analysis and the fluorescence spectrum of the title compound reveal its good thermal stability and a strong green luminescence at room temperature.
