Reaction of AgNO 3 and 2,2′‐bipyridine (bipy) under ultrasonic treatment gave the title compound, [Ag(C 10 H 8 N 2 )(NH 3 )]NO 3 . The crystal structure consists of dimers formed by two symmetry‐related Ag I –bipy monomers connected through intra‐dimer π–π stacking and ligand‐unsupported Ag...Ag interactions. A crystallographic C 2 axis passes through the mid‐point of and is perpendicular to the Ag...Ag i (− x + 1, y , − z + ) axis. In addition, each Ag I cation is coordinated by one chelating bipy ligand and one ammine ligand, giving a trigonal coordination environment capped by the symmetry‐equivalent Ag atom. Molecules are assembled by Ag...Ag, π–π, hydrogen‐bond (N—H...O and C—H...O) and weak Ag...π interactions into a three‐dimensional framework. Comparing the products synthesized under different mechanical treatments, we found that reaction conditions have a significant influence on the resulting structures. The luminescence properties of the title compound are also discussed.
