Abstract: | Reaction of AgNO3 and 2,2′‐bipyridine (bipy) under ultrasonic treatment gave the title compound, Ag(C10H8N2)(NH3)]NO3. The crystal structure consists of dimers formed by two symmetry‐related AgI–bipy monomers connected through intra‐dimer π–π stacking and ligand‐unsupported Ag...Ag interactions. A crystallographic C2 axis passes through the mid‐point of and is perpendicular to the Ag...Agi(?x + 1, y, ?z + ) axis. In addition, each AgI 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. |
