Abstract
In the title complex, bis{μ-1-[(1H-benzimidazol-1-yl)methyl]-1H-1,2,4-triazole}disilver(I) dinitrate, [Ag2(C10H9N5)2](NO3)2, the AgI ion is nearly linearly coordinated [N—Ag—N angle is 155.72 (14)°] by two 1-[(1H-benzimidazole-1-yl)methyl]-1H-1,2,4-triazole (bmt) ligands. In addition, two bmt ligands link two AgI ions, forming a dinuclear unit with an Ag⋯Ag distance of 5.0179 (15) Å. The whole complex is generated by an inversion centre. The dinuclear units and the NO3 − counter-ions are connected by N—H⋯O hydrogen bonds and weak Ag⋯O interactions [2.831 (5), 2.887 (5) and 2.908 (5) Å], leading to a three-dimensional structure.
