The synthesis of the title salt, [Ag(C6H7N4)2](NO3)3, was carried out employing a 1:2 molar ratio of 2,2′-biimidazole and silver nitrate respectively. The cation has crystallographically-imposed C2 symmetry with the metal atom in an almost linear coordination environment [N—Ag—N = 177.01 (17)°]. The crystal structure displays N—H⋯O and C—H⋯O hydrogen-bonding interactions.
The synthesis of the complex is described by Hester et al. (1997 ▶). 2,2′-Biimidazole was prepared in a manner similar to Debus (1858 ▶).
